molecular electron spectroscopy

Determination:

a method to determine geometrical structure of molecules by their microwave spectra associated with transitions between rotational energy levels.

Description:

The energy of a molecule's electrons movement, in accordance with the quantum mechanics principles, is equal to certain discrete values. Having absorbed photons, electrons transit into a state with higher energy; the so called excitation occurs. Depending on how high the absorbed photon energy is, ...
