Quantum Chemistry: Variation Theorem || Easy Approach || Solved Problems 

Such an incredibly amazing, simplest and complete explanation. The best video on Variation theorem. I have struggled so much in understanding this theorem. But after watching this video I am so much in state of solving questions based on this. Thank you so much. You are a wonderful educator. U explain every little detail and point with so much ease and patience. And yes, i am from biology background. Yet in first go, i understood it so well from this video.

Sir the way you explained i would like to give 1 lakh likes or more even if youtube had that option of giving more than single like. Thank you very much sir. your way of explanation is too much good. Hats off to you sir. And sir please make more videos from quantum chemistry because we students are from very unprivileged area and it is because of your videos we are learning chemistry.

E^2-3E-4=0 and min energy = -1

Most awaited video. I was searching for this type of a calm video, with a lot of thanks from kerala.

You are doing Awesome work Sir.. All your Classes added thousand fold Confidence to our Preparation..Thank you So much Sir..

Thank you so much sir. Try to add some more topics from quantum chemistry why because quantum chemistry is huge topic even maths background students are also not able to understand thus.

Your efforts are always appreciable

You are an excellent teacher Sir....Truely Inspirational....keep going....All the best wishes.....

Ground state energy is -1 Excited state energy is 4

Sir waiting for perturbation theorem ....nice explanation Sir.

Wow sir very nice thanku sir ji...🙏🙏😊😊

I love ur teaching skills

Sir please make vedio on stastical thermodynamics ...

Sir I requeste you to create a video of perturbation theory ....

Sir the answer of the question you gave for our practice was " -1 "....Sir, I think there was a mistake while solving i.e part-4 ( Maxima and minima kind of question) when dE/dC = 0, how h-cross will come over there ...???🤔

Sir perturbation theory pr jitna jldi ho ske bna dena video plzzz

I have one doubt sir...Sorry if I ask as misunderstood, h cross c /2m in question...But how did it converted in 32.24 min h cross ^2/2m.. sir please check whether the given E value correct or not ..In question part..

sir your explanation is very nice thankyou so much

Thanks sir 🙏🏻🙏🏻

Thank you sir...Your explanation making the concept very clear...

Superb Sir

Thank you so much sir.,I understood clearly.,I like your way of teaching.,and the answer for the last question is -1

Sir you are too good.

Is the energy of trial wave function also greater than the excited state?ny xplanation or something,just wanted to know

E = -1 and 4 And min energy -1

Sir in the last questn , the value of c^2 = m^2w^2/4h and in value of c where h^2 is coming out

Great great great sir... Sir iam a big fan of you...

In last ques how it become h cross square at dE/dC=0

Sir you mentioned the trial wave function that has more linear perameter, will have the nearest value of E exact. And E trial is greater equal to E exact. But u did not mention which trial wave function have greater E.

Minimum energy= -1 thank you sir nice question session 🙏🙏

Thankyou so much sir......sir please make a video on H atom

How are you writting hcross square ??

I think this is the only one vdo that approaches in a very soft manner. min energy -1

The quadratic eqn is E^2-3E-4=0, then it solve gets 4 and -1 min energy is -1, And another... Pls tell brother when Ur preparation especially this chapter, how u prepared strategy...

Very useful...Thank U So Much Sir..

Sir it is really very helpful. Thank u sir..

This pen and paper method is the best in the world

Thanks sir!

sir, at 33.18, while equating dE/dc=0, how h-cross became h-cross squared?

I found the minimum energy as -1, please tell me if it's true, and also tell if practicing these three or four types of questions for this topic is enough, or do I need to grind more

Please upload more videos on youtube before upcoming exam.

Sir, at 33:24 time you had written down the wrong expression of dE/dc .

Thank you sir...

Sir in last question min. Value of energy is -1 hai.. is it right

Sir in last question from where h cross has came

Aap pls perturbation theory pe b upload krdo..with triks nd all

Sir in trial wave function problem E= h cross(2)c /2m but u wrote on that h cross c/2m in that way doing that root h cross obtain plz once check that

Please solve question of gate 2019 perturbation problem?

Sir how to calculate node sir

Eq is Esqure-3E-4=0

Thank u so much sir🙏

Second question mein aap kaise node calculate kar rahe hai samoj mein nahi আ raha hai

Awesome sir

Sir pls explain me the sattelite peak ques. Of spectroscopy of dec2018

Wow this is a great channel indeed, thank you sir for clear explanations. @Stellenbosch_University

thanku very much sir

in question last but one ... it should be hcross squared otherwise the answer is wrong

Min energy is -1 Nice sir

Sir but I got 0.5 in ground state energy

Super sir

the answer for the practice question is -1.46 is it correct

Actually initially you have not put that's little bit confused

U r too good

Sir differentiation wale quese h2 sir Kaha se aaya

Mini. Energy will be -1 sir 😊

-1 is min value and 4 are max

Min energy is - 1 and maximum 3

Minimum energy -1

-1 and 4

Nice vdo

Yeah !

Minimum energy will be -1

Gs energy - 1

-1 hai sir answer ☺☺

answer is -1

Minimum energy= -1

E=-1

Sir kindly explain in hindi also. Please please sir.....

+3+_1 sir

Thank you sir

Thank u sir..

Thnq so much sir😊

Thank you sir ☺☺
