Nice video sir..u have a lot of patience.. I have learnt a lot from u..not only chemistry topics but even that fighter attitude & all.. Thanku sir.. U are a role model for many students..
Don't have words to express my gratitude to u sir...after 10 days there is my final exam of spectroscopy......before watching ur videos I was soooo worried....by now m preparing from ur videos....n they r really very helpful .....Sir plzzzz make video on NMR of paramagnetic substances in solution ....Thanks again sir...
thanks for this and other two lecture on quadrupole and spin cross over . I'm searching for good video lectures on mossbauer spectroscopy (MS) for past 1 month . i saw your video but never checked it .may be because I'm physics student and whenever I saw gate chemistry I just scroll down. my bad .....:p I need to give a presentation on MS in my class and its case studies in research but can't understand its application to structure determination and isomer shift application .your lectures helps me a lot in understanding these . thank you so much . keep it up ...
thank u so much. first time I'm going through the mossbauer spectroscopy. I got a clear idea abt this. i think the clarity of the video is not that much a problm
Sir, The effective nuclear charge is the net positive charge experienced by valence electrons. It can be approximated by the equation: Zeff = Z - S, where Z is the atomic number and S is the number of shielding electrons. How can the valance electrons shield the the elelcrons inner shell?
At 31:52 min of the video you told that Fe(+2) low spin has higher isomer shift than Fe(+3) high spin. This is not clear to me because in Fe(+2) low spin there is no eg electron whereas in Fe(+3) we have 1eg electron available in it . In that case as eg electrons are more effective in shielding the s electrons. Than i feel that the order must get reversed. Plz explain sir.I am clear on this.
if Mossbauer spectrum of FeCO5is recorded in the presence of magnetic field the original spectra with two lines changes into how many lines ? plzz explain sir
What is d difference between mossbauer nuclei n gamma source ..r they same.. r different cos a question was asked in June 2013 ..which is mossbauer nuclei..139^I,57^Fe, 121^Sb,57^Co
sir can u plz tell how many peaks potassiumhexacyanoferrate n potassiumpentacyanonitrosyl ferrate.....show in mossbaeur...plz sir answer it.... singlet or doublet...will potassium show different peak....plz solve it
this video was extremely useful .... Thank you sir !! by the way , we r still waiting for the 5th video of ur group theory lecture series ... plz post the 5th video 😇
Hello sir ..... Please solve this problem Q. Interpret Mossbauer spectra of FeSO4, 7H20 from given data ( given , δ= 0.119 aqnd 0.130 cm/sec, Δ EQ= 0.32). Thanks
Sir if it so....dn in case of tin is it that in presence of pi acceptor ligands like CN CO responsible for formation of low spin complexes will lead to decrease in d el density ie increase in s el density and hence increase in isomer shft?
I am very much benefited by this lecture.....my concept becomes clear now...thanks a lot sir
Nice video sir..u have a lot of patience.. I have learnt a lot from u..not only chemistry topics but even that fighter attitude & all.. Thanku sir.. U are a role model for many students..
Nice video sir. The quality of video is not important, the chemistry is important, and you explained it very well. Thank You sir.
I agreeee
True

Thank u sir ....I have been waiting for dis topic ...finally mossb spectroscopy.. Once again thank u.
This video was very useful for me. Thank u sir..
Nicely explained🙌,thank you
Excellent video.very clear explanation Sir👍
it really helped me to understand clearly..awesome☺...thank you soo much sir.
Nice video. Can you please post a photo of what you have written structure of two different compound of iron.
Thank you
sir u explain the things in much simplified manner.....thank you
Thankyou sir, you explained Mossbauer very well.
thank u so much. first time I'm going through the mossbauer spectroscopy. I got a clear idea abt this. i think the clarity of the video is not that much a problm
Sir,
The effective nuclear charge is the net positive charge experienced by valence electrons. It can be approximated by the equation: Zeff = Z - S, where Z is the atomic number and S is the number of shielding electrons.
How can the valance electrons shield the the elelcrons inner shell?
Excellent. can u explain little bit hyperfine splitting in mMS
Very interesting and very useful
Amazing explanation sir
waiting for Mossbauer spectroscopy part 2.. part 1 really help me to understand basic concepts..
Thanks sir, its very easy after ur teaching..
sir ur every video is very knowledgeable. ...
Thank you very much sir... I got a clear idea now.
sir, while drawing the graph how the isomeric shift influence....... can you plz explain
sir it's very good video, can you provide NMR spectroscopy lecture, how integrate solve spectra
Inspite of blurred parts sir ... its very helpful to understand the topic nicely
At 31:52 min of the video you told that Fe(+2) low spin has higher isomer shift than Fe(+3) high spin. This is not clear to me because in Fe(+2) low spin there is no eg electron whereas in Fe(+3) we have 1eg electron available in it . In that case as eg electrons are more effective in shielding the s electrons. Than i feel that the order must get reversed. Plz explain sir.I am clear on this.
even iam not getting this ..can u please explain??
Sir, is not Fe +2 a d6 system?
If the s electron density decreases near nucleus for high spin case , how will the shift increase ?? It should have decreased as well.
Excellent explanation...sir...thnx a lot...
sir can u plz tel me wat r d criterias for a molecule should be mosbauer activ????
Great.. working really hard... Ur speaking skills are also appreciateable
In +3 oxidation state of iron the configuration should be t2g(5) not t2g(6) .... Time 29 :11
i guess it's kinda randomly asking but do anyone know a good site to stream newly released movies online?
@Gannon Graysen lately I have been using flixzone. You can find it by googling =)
if Mossbauer spectrum of FeCO5is recorded in the presence of magnetic field the original spectra with two lines changes into how many lines ? plzz explain sir
sir, if eg orbitals better shield s electrons,how come electron density near d nucles decrease? what s d relation?
Nice explanation... thank you...plz take questions from this topic
Sir thank u so much...sir plz do lecture on mass spectroscopy.... would be a gr8 help
Bestest videos.....👌👌
Thnku sir.. I think video quality is not a big issue...By watching 2-3 times u will be able to understand everything...
very nice video sir. I am unable to find out your zeeman effect video after esr..can you give me the link or tell the title of it?
even i am searching for.If u get pls let me know.
oh..ok..
Sir sn+2 will have highest isomer shift or Sn+0 ....
Which book should refer for jrf chemistry...
Very helpful for me...thanks so much☺️
but sir how to check whether the given atom is expanding or contracting time????
When you post the nxt video
What is d difference between mossbauer nuclei n gamma source ..r they same.. r different cos a question was asked in June 2013 ..which is mossbauer nuclei..139^I,57^Fe, 121^Sb,57^Co

plz tell me how to determine coordination no.,oxidation state in Mossbauer spectroscopy
Hello sir ..... Please solve this problem
Q. Interpret Mossbauer spectra of FeSO4, 7H20 from given data
( given , δ=
0.119 aqnd 0.130 cm/sec, Δ EQ= 0.32). Thanks
Ty bro...it really helped me in xam
i am unable to understand why is it recoil free ?
@@gatechemistry i don't have that whatsapp anymore .
Sir,how by back donation s el density increases...is it bcoz of decrease in d el density bcoz of back donation?
Sir if it so....dn in case of tin is it that in presence of pi acceptor ligands like CN CO responsible for formation of low spin complexes will lead to decrease in d el density ie increase in s el density and hence increase in isomer shft?
very helpful it's .thank uh sir
