Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.Question 2: The absorbed energy comes from photons travelling with a certain frequency.

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.Question 1: I think it could be A. When the CO absorbs energy it gets excited and so we go from ##E_n \rightarrow E_{n+1}##. ##E_n## are...

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.Okay. Light is made of photons. Different colour photons have different energies. Intensity is the amount of energy per second per unit...

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.1. The only way our sample of CO would lose energy is to give it out via em radiation. Those dips in rotational energy are photons being...

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.Okay, I am going to answer one of your questions. 1. The dips in energy represent energy loss due to photons of light being omitted...

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.The difference between adjacent energy levels ##\Delta E = \frac{\hbar^2}{I}n##. But what in the statement of (c) tells us that we need...

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.I am still not clear on how to proceed with part (c) @kuruman

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.If our ground level is zero then: ##E_n - E_{ground} = E_n = \frac{h^2}{2I}n(n+1)##?? I am looking through my textbook to see where...
-
Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.I see. No is the answer. The equation that I state originally appeared in the following form: $$L^2 f_n^m = h^2 n(n+1) f_n^m$$ where...

Hhmparticle9 posted the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles in Advanced Physics Homework Help.I have included a screenshot of the question as we need to use the figure for the last part of the question anyway. For part (a) I...

Hhmparticle9 reacted to TSny's post in the thread I I would like some assistance working with commutators with
Like.
Your method is fine. To shortcut it, you can note that all factors in ##[y p_z, x p_z]## commute among themselves. Thus, ##x##... -
Hhmparticle9 posted the thread I I would like some assistance working with commutators in Quantum Physics.I am starting to realise that I am struggling with commutators, and I want to address this before moving on. This particular example...

Hhmparticle9 reacted to ergospherical's post in the thread Calculating ##\langle zHz \rangle## in different ways with Like.
Right. The "quick way" often means "here's this esoteric trick that my professor taught me (and his professor taught him, etc.) that...

Hhmparticle9 replied to the thread Calculating ##\langle zHz \rangle## in different ways.I really doubted myself because I found the "long way" to actually be shorter than the "short way". Thanks again guys.

Hhmparticle9 reacted to ergospherical's post in the thread Calculating ##\langle zHz \rangle## in different ways with Like.
That's the correct "long way" (or at least, one of them). How you go about evaluating that is up to you... but there's certainly a few...
