In the comments I've observed that many of you want to know that how to assign values of nx ny and nz for 3rd or 4th excited states. See it is very simple, in 3D box for ground state we have (111) as (nx, ny, nz) values, for 1st exited state we have (112) or (121) or (211) any of them as all these will be degenerate levels (see my video on Degeneracy of Energy Levels) For 2nd excited state it will be (122)or (212) or (221). For 3rd excited state it will be (222) For 4th excited state it will be (223) or (232) or (322) Likewise you just have to increase the value of any one of the nx ny or nz when you go from one excited energy level to higher one. I hope it's clear now. 👍
Thanks for Solving the 1D potential well "problem" of us. Please help us in understanding the Harmonic Oscillator and Rigid rotor. Both of them will help us in understanding the vibrational and rotational spectroscopy
Thank you so much sir!!!!!! It means a lot for us you are making such efforts for explaining all important topics in CHEMISTRY. PLEASE KEEP POSTING MORE VIDEOS 👍
Please do problem where wave function is sine or cosine over interval o to L. I want to see how upper and lower limits of the integral change. Please. Thank you. From South Africa.
Please upload more videos on quantum chemistry . Up to now I did not find this kind of explanation and it is very easy for me to understand .please upload perturbation and variation theory
The difference in energy in a 1D box is 6 units of energy in the same units.what is the difference in the energy levels of ñ=3 and n=2 for the above system
Sir can you pls tell this question answer What is the probability of locating a particle of mass m between x=L/4 and x=L/2 in a 1-D box of length L? assume the particle is in the n=1 energy state
sir... why we take potential energy as zero. If we compare this 1D system with the atom, then the electron never have zero potential energy in the atom( it is negative ). then why we take zero here??
Hi .A particle is in a box of length L. Suddenly, the length of the box is increased to 2L. What happens to the energy levels shown in the figure? Please answer me
11:04 Bro, considering the C.F of the DE I'm getting sin(kx) + cos(kx) only as e^0 is 1. So, why there's 2constants named A and B? I'm perplexed.. Help me with that?
Sir, pls do a complete course on organometallic chemistry right from basic like 18e rule..... to coupling rxns like Sonogashira, Heck etc. for CSIR NET/ GATE in UNACADEMY 🙏🙏🙏 Hope u'll do so, Sir..... Eagerly waiting for the course. And thnx a bunch for the tutorials, ur videos r too nice n helpful!!!!

Super sir. Thank u. U've driven away my fear about quantum chemistry...👍👍👍
U r amazing sir..!! Now im so interested in quantum chemistry ❤ keep going sir👍👍👍
Thank you so much sir you are the best teacher👌👌👌
Sir apne 2D ke liye 1st and 2nd excited state and 3D ke liye 1st and 2nd excited state ka value kese likha...
Thank you so much sir for uploading this video(quantum chemistry)
You're welcome 😊
Please upload more videos on quantum chemistry . Up to now I did not find this kind of explanation and it is very easy for me to understand .please upload perturbation and variation theory
Thank u sir ..please upload more vedio on quantum chemistry problems & topics
Yes sure 👍👍👍
Gud explanation
Kindly also make video for application of schrodinger wave equation to hydrogen and hydrogen like atoms
awesome tqqqq soo much sir
thanks from gujarat
Sir kindly give some idea on harmonic oscillator
Plz sir keep it up....
Thank you 😊
Please explain the postulates of quantum chemistry
Sir in this ques the first part for 1D means particle in 1 dimensial potential box???
Send more videos on quantum sir
OK I will try to upload
The difference in energy in a 1D box is 6 units of energy in the same units.what is the difference in the energy levels of ñ=3 and n=2 for the above system
In 07:40 you miss the sign of mius when you multiple 2m /h
Sir concept of probability wahi hai Kya Jo apne sig ki value btaye hai?
Sir , apne mulliken notation of irreducible represents ka concept the gya hai plz tel ...June 2013 m aya hai plz
Sir at 24:40 I understood for ground state,for oll 1 , 2D & 3D .but sir excited state me nx NY ki value kese put kre samj ni aaya ..😭😶😶😶😶
I've replied in the comment and pinned that comment. Please read it. I hope you'll understand that.
Sir can you pls tell this question answer
What is the probability of locating a particle of mass m between x=L/4 and x=L/2 in a 1-D box of length L? assume the particle is in the n=1 energy state
Pls sir reply quickly by through a link
Why did you substitute with k² and not simply k. I'm curious to know. I'm 70 year old former science teacher keeping up to date.
Thank you.
Sir upload video for previous 5years solutions

You're welcome 😊😊😊
Hi .A particle is in a box of length L. Suddenly, the length of the box is increased to 2L. What happens to the energy levels shown in the figure? Please answer me
Energy decreases by a factor of 4
It is easy question ,put the value of L in energy formula
11:04 Bro, considering the C.F of the DE I'm getting sin(kx) + cos(kx) only as e^0 is 1. So, why there's 2constants named A and B? I'm perplexed.. Help me with that?
For second excited state in 3d all values will be 2?
What are the units of wave function in 1d and 3d box?
Sir is calculator allowed in csir exam ? Because the calculations of electrochemistry numericals are very time consuming .
No, calculator is by far not allowed in any CSIR Exam. I'm not sure about the upcoming ones but till now they haven't allowed for it.
I understood quantum mechanics at the age of 14.
😄😄
