14.3.1 Principle and analytical information of IR spectroscopy. IR spectroscopy is an analytic method based on the absorption of IR radiation by vibrational excitation of lattices, surface groups, molecules, etc. in each physical condition. The absorptions are always associated with a change in the dipole moment of the molecule/material. Spectroscopy - Spectroscopy - Theory of molecular spectra: Unlike atoms in which the quantization of energy results only from the interaction of the electrons with the nucleus and with other electrons, the quantization of molecular energy levels and the resulting absorption or emission of radiation involving these energy levels encompasses several mechanisms.

V+(N2)n clusters are generated in a pulsed nozzle laser vaporization source. Clusters in the size range of n = 3в€’7 are mass selected and investigated via infrared photodissociation spectroscopy in the Nв€’N stretch region.
