appreciable effort... it would be better if you start a series of short lectures upto 30 min in which you can describe each and every aspect of a particular topic. i am telling you this because i feel you have a good art of teaching.. of course that will take time but i think you should forget about the nearest exam and think about those who has to serve for long... descriptive topics make a person to gain real knowledge...

[@AllBoutChemistry]

Thank you for this detailed feedback, I'll definitely try to work on this.

[@birkishoremahto1764]

Provide lec. on variation and perturbation theorem

[@sumanmondal6598]

Thank you so much sir.... Waiting for more videos for upcoming CSIR NET exam...

[@AllBoutChemistry]

😊

[@abdulrauffaiq]

Thanks all about your vedios that I need more vedios about quantum chemistry. I am a student the physical chemistry at Kurdistan UUnivesity in Iran. Then I totally need a bout quantum chemistry. Please make a more vedio a bout quantum chemistry by numbering.

[@aabidhamid5889]

Sir please upload more videos on Quantum Chemistry, Ionic Equilbria and Data analysis. Thanks a lot sir.

[@AllBoutChemistry]

Ya sure I'll try to make videos on them too.

[@chemikamesh4788]

Super..... If u have time means, Go-ahead with variation theorem, perturbation....

[@AllBoutChemistry]

Sure, I'll try to make videos on them too

[@bhoopsingh153]

I'm a physics student but this is very useful for me

[@ShivamModiOfficial]

when we got where ms=0; so why we only add? why cant we subtract?

[@angelriyavarghese5863]

sir can you make a class on hydrogen atom and related questions of quantum mechanics. If you teach ,the difficult topic even become easy.

[@chintadasatyavathi4960]

very nice sir thankyou so much happy to see your lecture

[@nehanishad4231]

Thanks you. Plz make more video important for June net exam. I also follow in unacadmy.

[@rosa-fr5fo]

Thanks sir ..☺

[@AllBoutChemistry]

Welcome dear 😊

Aab Jake samj aya....thnx a lot sir

[@khesalafzal9242]

Thank you. Clear 🙏🏻

[@karandoda1835]

22.30 why we cant subtract? it is also a solution??

[@chakrapanipani2912]

Sir make a full video on quantum chemistry. Because most of organic students facing difficulties in this

[@villageyoutubefact9611]

Really u r my god...

[@dishasingh5244]

Sir june 12 Question me addition kyu hua h substraction kyu ni hua???

[@birkishoremahto1764]

Thanks sir

[@keyapal9334]

Pls make video on huckel determinant and delocalisation energy..

[@user-to3fx2do4d]

Hello sir. Generally, Slaters Determinant (the anti-symmetric wave function) is not the eigenfunction of the system. Example. Please suppose the system composed of two electrons. Electron 1 is in a hydrogen atom. Electron 2 is in a helium ion He+. rA, rB : the position of each nucleus. The two electrons are far enough. H1=(p1^2/2m)-(e^2/4πε0❘r1-rA❘), H2=(p2^2/2m)-(2e^2/4πε0❘r2-rB❘), H1φA(r1)=EAφA(r1), H2φB(r2)=EBφB(r2). Hartree productφA(r1)φB(r2) is the eigenfunction of operator H1+H2, and lead us the energy of the system EA+EB. But, another productφA(r2)φB(r1) is not the eigenfunction of operator H1+H2. (Please calculate it. It's very easy.) Therefore, the anti-symmetric wave function ψ=φA(r1)φB(r2)-φA(r2)φB(r1) is not the eigenfunction of the system.

Thank you sir

[@prateekahuja5086]

Respected Sir, at 25:13 the selected term doesn't represent triplet state and you misunderstood ms=0 with (2S+1=0). Both are different. ms is related to orbital angular momentum where as 2S+1 is purely dependent on total spin of the electrons present in the system. According to me the correct ans should be c

[@aswanipv7919]

👌explanation sir

[@MASChemistry]

Awesome..

[@lookaway8496]

What is the difference between Slater determinant and secular determinants?

[@Ayush-cs5tw]

Why option D even though it is symmetric.

[@angelriyavarghese5863]

at 21:55 in the first question as it is given ms=0 as well as triplet state it is confusing

[@poojajoshi2014]

Thank you sir☺️

[@nittansingh7545]

sir plzzz mention important topics from quantum chemistry

[@gauravjyotid.kalita3417]

Sir if we see the spin parts of the wave functions with spins ms = 0, we took the sum i. e. (Alpha 1beta 2 + beta 1 alpha 2), my question is why didn't we take the difference, i. e.( Alpha1beta2 - beta 1alpha2), because negative part is anti symmetric and positive part is symmetric and both are indistinguishable after finding their linear combination, which naturally gives a constructive and destructive wave function, constructive for plus spin part and destructive for minus spin part. So, being antisymmetric, the negative part was in a better position to be the answer, please clarify Sir?

[@akb0014]

Because orbital part is antisymmetric due to presence of one g and one u.. So over all u

[@samitadutta97]

Kal k exam may slaters determinate ki ans kya hoga?

[@piccsirnetchemistry2433]

Make more video on quantum sir

[@aabidhamid5889]

Dear Sir, Can you please make video on main group elements.... Important topics. Thanks in advance.

[@deekshasaini9607]

Sir plz upload more questions...

[@abineshkrishnan843]

Please pass some references book...

[@sumansarkar8017]

For the june12 ques why not opt b?

[@hemlatabhatt2865]

Isme 25.15minute m hm subtraction wala combination kyu nhi le rhe,,,, please ans

[@gauravjyotid.kalita3417]

My question is same, why not the subtraction part, because it is antisymmetric so it has more chance to be the answer

[@pallavjyotiarandhara]

Please tell me the expected cut off for CSIR NET dec 2018

[@AGCHEMBYABHISHEKGOYAL]

Ms= 0 is in singlet state n sir

[@ankithamenon8398]

I too have the same question
