    sir ek bolta hu dil se...bahut si sir ka tution style or skill dekha hai....par sir nobody is as good as you....
    aapke videos dekhke lagta hi nhi chemistry difficult hai...
    par asal me maja aane laga hai....
    thank you sir for everything...
    love you sir...
    aur sir nmr ka series jaldi khatam kar dijiye...humhe bahut intezer hai

    Sir your way of teaching is just so praiseworthy. You create this curiosity in us by placing questions first and then make us think over it... it's fun and we learn topics with an ease. I am just so obliged to find your channel. Keep up the good work sir.

    Sir no words...... literally kya smjhaaya hai aapne NMR Abhi tak....kisi bhi teacher ne itna conceptual aur details mein ny pdhaaya kbhi....aur aapke pdhaane ka Andaaz shuru se hi aapne aap mein bht bht bht bht hi jyaada accha rhaa hai.....

    2H (Deuterium) I = 1, So 2H NMR Active, however, If you consider 1H NMR, in this case, 2H inactive.

    I am calling from Bangladesh, first NMR spectrometer came to us in 1966 at CSIR. Dhaka . There we used NMR for no of H in molecule , also structure of organic compound at early stages but nmr became out of order, no body could use the machine

    Sir mera ek doubt hai.. Apne bola tha ki external magnetic field jyada hoga to larmor frequency bhi jyada hoga... Aur us hisab se ch3br ki larmor frequency jyada hogi tms se.... Par aap abhi keh rahe ho ki tms ki frequency jyada hogi ch3br se... Sir ch3br jyada deshielded hai tms se to vo jyada external magnetic field feel karega or frequency bhi jyada hogi to fir tms ka frequency kaise jyada ho sakta hai?... Sir please reply

    Thankuh sir....lecture 15 me ek doubt hai....aapne bola ki external magnetic field zada toh precision b..zada but jb isolated hydrogen aur kisi aise hydrogen ki bt krte hai jo carbon ke sth ho toh carbon ke sth wala hydrogen high frequency prr absorb hoga...aapne jaise btaya oh low frequency prr absorb hota hai nd ch3 high coz in ch3 shielding effect zada hai..Mera doubt yeh hai ki maan le 2 testla external magnetic field de ek isolated system ko uski vhjse hum assume kre ki larmer freq 50 hz hogyi toh absorbtion b..50 hz prr hoga on the other hand agr hum 2 testla external magnetic field lgayege kisi aise atom prr jha electron ki wjhse zada shielding ho toh Puri 2 Tesla magnetic field toh nucleus ko nhi pahuch payega nucleus ko jo magnetic field aayega wo subtraction hoga applied magnetic field and induced magnetic field ka...it means ab magnetic field km hoga nucleus ka uske acc toh larmer frequency jo 50 hz thi pehle ab wo b..km hogi kyunki aapne btaya tha external magnetc field directly proportional to larmer frequency toh larmer frequency km toh incident radiation jb km frequency prr hoga tbhi absorption ho Jana chahei..prr aapne toh yeh bola tha..shielding zada toh absorption high frequency prr hoga?...I hope aap Mera doubt smj gye honge ...sir clr my this query

  • @riyabisht1297

    Sir, in this video you use operational frequency term for precessional frequency at 3:30 sec, it is confusing 😢 you said that "isse m operational frequency kahu ya precessional frequency kahu ya resonating frequency kahu "

    Sir, I appreciate ur work but the maths done is wrong ...we can't multiply any equation by any no. we want or divide the equation with any no. we want ...
    MHz=10⁶Hz and in place of MHz we can only write this no. & we can't multiply it with 10⁶ as we have only Hz as a unit of difference...
