It is indeed refreshing to get such a content for free. Thanks a lot, from France^^

Haha, la particule est libre ainsi que libre, ici. Merci, et salut

Thanks it's really rare to find topics like this on KZbin Please upload more and go deeper , cover in depth thank you 🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼

[@PhysicalChemistry]

Glad it's useful to you. Thanks for the response

Where were you two years ago when I took this class 😭 😂 I’ve been literally watching these videos for fun because you make it so enjoyable.

[@PhysicalChemistry]

Haha. Of course you're watching PChem videos for fun. What else on the internet could be nearly as entertaining?

[@mortezakhoshbin]

@@PhysicalChemistry nothing! this is second time i am reviewing the lectures and are so enjoyble. thank you again for making it such simple ❤️

[@conormcdaniel2066]

Is there a reason the eigenvalues of the Hamiltonian cannot be negative? If they were, wouldn't the exponential function still work?

[@PhysicalChemistry]

Yes, that's possible. But in order for the eigenvalue k² to be negative, you would need an imaginary value for k. It turns out that *is* a perfectly good solution, but it gets us back to the oscillatory behavior of the sin(kx) solution.

@@PhysicalChemistry thank you for your response! That makes sense

Hi professor Steven, I found this video didn't pop up where the next video should watch, so may I ask which playlist should I follow for next video(is the One-dimensional Particle in a Box?)? Thank you very much.

[@PhysicalChemistry]

Yes, One-Dimensional Particle in a Box is the next video: kzbin.info/www/bejne/fpyQn6eKlMqCntk
