I think that we are both using the word vibration in a different way. I was using it to mean an actual physical vibration of something like a spring which is used to illustrate the mechanism of IR absorption though fallaciously as it would seem if nothing is actually vibrating that way. You, on...

In your first message you say that there is no fluctuation of charge distribution in the molecule occupying excited states and then in your second message you say that the molecule vibrates in response to a perturbation as it transitions from say the ground state to some excited state. Doesn't...

By coupled here I assume you're not referring to rotational vibrational coupling and are just considering the transition between the pair of vibrational states. Also do you mean absorbed and not emitted?

Thanks for the reply. Classically electrons moving around the nucleus are accelerating charge and therefore should lose energy in the same way classically a vibrating bond is accelerating charge and should also lose energy. No? I've seen illustrations showing that a passing IR wave basically...

In IR spectroscopy, bonds vibrate and therefore there are moving charges and usually a changing dipole. If accelerating charges cause EM waves to be given off due to the changing electric field then shouldn't the vibrating bond be constantly emitting photons and therefore losing energy in a...
