Spectroscopy - Spectroscopy - Energy states of real diatomic molecules: For any real molecule, absolute separation of the different motions is seldom encountered since molecules are simultaneously undergoing rotation and vibration.
The rigid-rotor, harmonic oscillator model exhibits a combined rotational-vibrational energy level satisfying EvJ = (v + 12)hν0 + BJ(J + 1). A discussion of rudimentary group theory advances to considerations of the rotational spectra of polyatomic molecules and their vibrational and electronic spectra; molecular beams, masers, and lasers; and a variety of forms of spectroscopy, including optical resonance spectroscopy, coherent transient spectroscopy, multiple-photon spectroscopy Cited by: The Electronic Spectroscopy of Polyatomic Molecules.

Polyatomic vibrations, briefly: For a nonlinear N-atomic molecule there are 3N-6 vibrational degrees of freedom (= number of vibrational fundamentals).
This comes from 3 degrees of freedom, for the 3 spatial directions, from each atom, -3 for molecular translation, -3 for molecular rotations.

ADVERTISEMENTS: Some of the important types of Spectroscopic Techniques are as follows: Type # 1. Gamma Spectroscopy: Gamma spectroscopy is a radionuclide measurement method. While a Geiger counter determines only the count rate, a gamma spectrometer will determine the energy and the count rate of gamma-rays emitted by radioactive substances.
Gamma spectroscopy is an extremely [ ]. Although some of these may be degenerate if the molecular symmetry is high enough, the overall appearance of the spectrum is as a result generally very complex indeed.
