I have watched all 5 of your video lectures on quantum molecular theory. They are all very clear. You are an amazing teacher. I am a 60 year old digital chip engineer, who had no background in this field at all. And even I can learn this stuff. By the way, I happened to come cross one of lecture. Found to be super clear. Then just went one after another. Thank you very much for the education. Knowledge is an ultimate entertainment.

Oh my god, I am so grateful for this wonderful class! You are extremely didactic! I was using McQuarrie to study and I wasn't understanding anything! Thank you very much, Mr! This was really helpful!

this video will save me, tomorrow I have the physical chemistry exam, I still don't understand one thing, when is it necessary to use Ms and Ml? for helium we didn't use them, while for carbon we did, why?

You're an INCREDIBLE LECTURER. I understood nothing when I listened this topic at the classroom. Whilst, after watching this video, I Ioved this topic. Thanks for being an amazing teacher!!

I have one doubt. At 12:42, you are saying that in case of hydrogen atom, the energy associated with the 2p electron only depends on the principal quantum number 2. But at 15:47 you are saying that there are two groups of wavefunction having different energies corresponding to the same principal quantum number 2. This is confusing me. Please explain.

@TDanielCrawford 2 жыл бұрын

The energy levels of a hydrogen atom - without considering the spin of the electron - are proportional to -n^2, where n is he principal quantum number. If you include the electron spin, then the spin angular momentum can couple to the orbital angular momentum. For an electron in a p-type orbital, this leads to a *total* angular momentum of either J=3/2 or J=1/2, which are at different energies. In short, if you ignore spin, then the total energy levels of the hydrogen atom depend only on n. If you include spin, then they also depend on the total angular momentum. I hope that helps!

What a blast from the past. Prof Crawford taught me PChem2... now, 15 years ago. This clear and pleasant teaching style is really taking me back. It is amazing that I used to understand all of this stuff way back when, enough to get an A at least - very, very fuzzy now though.

Thank you so much for this incredible video! This lecture is by far the clearest explanation I have seen on YT, my only wish would be that you posted more videos as these are so tremendously helpful!!
