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.
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.
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 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 ...???🤔
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...
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.
If you have two trial wave functions, one which is made of linear combination of two wavefunctions having energy E1 and other with linear combination of 3 wavefunctions having energy E2 then energy of E2 will be closer to E(exact) and E1 will be away from E(exact). Among E1 and E2, E1 will be greater. Overall order will be E1>E2>E(exact) I hope this was helpful
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

Thank you brother, I'll try to upload more videos soon
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..
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
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.
Sir waiting for perturbation theorem ....nice explanation Sir.
I love ur teaching skills
Wow sir very nice thanku sir ji...🙏🙏😊😊
Sir you are too good.
Superb Sir
Sir please make vedio on stastical thermodynamics ...
sir your explanation is very nice thankyou so much
Thank you sir...Your explanation making the concept very clear...
Sir perturbation theory pr jitna jldi ho ske bna dena video plzzz
Great great great sir... Sir iam a big fan of you...
Minimum energy= -1 thank you sir nice question session 🙏🙏
Sir I requeste you to create a video of perturbation theory ....
Thank you so much sir.,I understood clearly.,I like your way of teaching.,and the answer for the last question is -1
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..
This pen and paper method is the best in the world
E = -1 and 4
And min energy -1
Thanks for that video sir 🙋🙋🙋
Very nice 👍
Very useful...Thank U So Much Sir..
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 ...???🤔
Can energy value be negative considerable
Because of Energy value = h cross (2) c/ 2m +mw(2) /8c but sir forget only wrote on that h cross c / 2m + mw (2) / 8c that was mistake sir made
Is the energy of trial wave function also greater than the excited state?ny xplanation or something,just wanted to know
In last ques how it become h cross square at dE/dC=0
In question only it must be h cross square by 2m
I think this is the only one vdo that approaches in a very soft manner.
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
How h^2 came.can u plz explain
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...

I hope this was helpful
@@AllBoutChemistry thank you sir
How are you writting hcross square ??
Sir it is really very helpful.
Thank u sir..
Thankyou so much sir......sir please make a video on H atom
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
Sir, at 33:24 time you had written down the wrong expression of dE/dc .
Awesome sir
Please upload more videos on youtube before upcoming exam.
Eq is Esqure-3E-4=0
in question last but one ... it should be hcross squared otherwise the answer is wrong
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
sir, at 33.18, while equating dE/dc=0, how h-cross became h-cross squared?
same question
@@souravpan3068 He made a mistake. The starting eqution itself carries h-cross squared.
Min energy is -1
Nice sir
Thank you sir...
Sir how to calculate node sir
Thank you sir
Sir pls explain me the sattelite peak ques. Of spectroscopy of dec2018
Thnq so much sir😊
Sir in last question from where h cross has came
Sir in last question min. Value of energy is -1 hai.. is it right
Please solve question of gate 2019 perturbation problem?
Aap pls perturbation theory pe b upload krdo..with triks nd all
Thank you sir ☺☺
thanku very much sir
Second question mein aap kaise node calculate kar rahe hai samoj mein nahi আ raha hai
Super sir
-1 is min value and 4 are max
-1 hai sir answer ☺☺
U r too good
Sir but I got 0.5 in ground state energy
Wow this is a great channel indeed, thank you sir for clear explanations. @Stellenbosch_University
Mini. Energy will be -1 sir 😊
Min energy is - 1 and maximum 3
Minimum energy will be -1
the answer for the practice question is -1.46 is it correct
Minimum energy -1
Sir differentiation wale quese h2 sir Kaha se aaya
Starting se hi h2 hoga.
Nice vdo
-1 and 4
answer is -1
Minimum energy= -1
Gs energy - 1
E=-1
Actually initially you have not put that's little bit confused
Yeah !
Sir kindly explain in hindi also.
Please please sir.....
+3+_1 sir
Thanks sir!
Thank u so much sir🙏
Thank u sir..
Thanks sir 🙏🏻🙏🏻
