Quantum Chemistry 3.3 - Eigenvalues and Eigenfunctions (Old Version)

[TMPChem]

Notes and Corrections:

6:34 The momentum squared operator should have hbar^2 instead of hbar.

7:06 The momentum operator should start with a minus sign. The momentum operator in the x-direction is [-i hbar d/dx].

I have been very pleased with how accessible and well-presented this series of videos has been. It has been an excellent primer for my PChem course.

Many thanks for creating and posting these - I am very appreciative.

Thanks, Jide! You're going to great in pchem because you're putting in the work.

Fantastic video on explaining what exactly an operator is achieving. Great way to give some solid footholds to grasp onto the beginnings of QC. I'll be watching all of your videos!

Shared your channel on Facebook with my entire class. THANK YOU!

[angiecfrmthebay]

Thank you so much for making this video!!! You angel of chemistry, you!!

[TheJfather]

it seems so simple now, but man in lecture i just had no idea what eigenvalues and eigenfunctions even meant in any fashion whatsoever, just something didnt click. Thank you so much this one thing cleared up so much.

Gotta start through the rest of these videos now

[leahosnos]

These videos are awesome. Thank you so much!

You have no idea how much you are saving me right now.

I am a biochem major and to graduate within in reasonable time I took quantum chemistry to fulfill an upper division requirement. I didn't take any pchem before so this has been really really hard, even with my above average math skills.

Simple concepts like these were hard to grasp because it was expected that we know them. Even now 1 month till the class is over I am struggling with these basic concepts (I understand them slightly- but not to the level the class requires) . I did terrible on the first test. And now I am 1.5 days away from test 2. So I am going to study like never before.

Thank you so much. So much.

Thanks to you I now will somewhat understand what I'm failing! :D

"you should be able to convince yourself that the root square of -1 is i" hahahaha so true

[imaginarypanda]

My physical chem prof doesn't explain any of the mathematics. This helped out a ton. 

[olajideolagunju]

Thanks so much!!! P.Chem 2 feels so much less intimidating!!!

7:13 Why do we take -i instead of +i?

[mohammadjj]

Are these the same concepts in Quantum Physics?

[Startpixie]

Hi.. at the very end shouldnt it be + or negative i ? Im not too sure, just checking :)

[SunilHembramofsanolia]

pardon me sir....but on lect#22(i.e lecture on avg. momentum) n alll other videos, you took p as p=-i*h/2pi(d/dx) but here you wrote p=i*h/2pi(d/dx), I think here it should be a -ve sign in momentum operator.

I have the opposite problem, my teacher explains the math too much. I was hoping more of a conceptual and maybe even an example problem
THanks
