I absolutely hear you

I remember studying up on braking radiation. I appreciate your putting this into perspective for when it comes to continuum radiation. Very clearly stated, and makes sense. Thank you for taking the time.

Thank you for suggesting that book and those specific chapters. And saw the write-up that says the book contains an up-to-date account of the optical physics of solid state materials. Very good..

Thanks so much. I had a feeling it was more than just vibrational modes. And, as for the molecular vibrations, when I was speaking of those types of vibrations in the past, on this thread, I meant as an aggregate -- a whole. I never meant to give the impression that I was looking at it as an...

I just saw your answer after typing my last post. Thank you. -- Both answers. I will go over what you just posted. Again, thank you.

Acknowledging those answers that were, in fact, very helpful, and complementing the authors in the process, is hardly ignoring 'the answers'. I never said that it requires a bit of time. And, again, just to clarify, I wasn't speaking of an isolated molecule a while back. I was merely trying...

I was referring to the whole, entire collective of an object (the system) and blackbody radiation (I made it very clear a number of posts back that I wasn't talking about an isolated molecule). Unfortunately, I've been misinterpreted throughout the latter half of this thread and portrayed as the...

You're killing me here :-/ Had just asked a question, that's all. But, I can understand your viewpoint and what you're saying..

You know, I've seen users in various related forums ask questions that show much less study and thought put into their area of interest/concern and get treated with more respect than that which you've shown me. If you'd chosen to be more focused, in your posts, on helping me with...

When it comes to all solids, I've seen things as a collective: condensed atoms and molecules (a lattice). For liquids and very dense gases: relatively condensed atoms and molecules (without a lattice). And dilute gases: isolated atoms and molecules. Also, from what I've been studying as of...

What is wrong with asking specific questions about the categories of transitions and how everything works together? This has nothing to do with seeing things in my own terms. As I stated in one of my responses the other day, I am looking at the system as a collective and was not taking about an...

Thanks for that link. I had that site bookmarked awhile back and lost it. Now found.

Thank you so much for your in-depth answer. First off, regarding the above, do you mean that the combined system (electron + nucleus) absorbs/emits the same photon? And, when you say 'combined system', that would be similar to just saying 'atom' (or molecule)? And the rotational state would...

I know, a lot to study. I had wanted to add this as part of my last reply. I included two quotes from this wikipedia page: https://en.m.wikipedia.org/wiki/Energy_level -- they are discussing the three types of energy transitions for a molecule:'Electrons in atoms and molecules can change (make...

I don't mean an isolated electron. I'm thinking of the massive amount of electrons that make up an object (say, a piece of wood). There, of course, would be billions of atoms making up the piece of wood, and would be a number of electrons in a good percentage of the atoms that make up the wood...
