High Resolution CARS Spectroscopy of Polyatomic Molecules (original) (raw)

Springer eBooks, 1996

Abstract

The investigation and analysis of rotation-vibrational bands through high resolution infrared and Raman spectroscopy is an important source of information on the structure of polyatomic molecules. By cw-CARS (coherent anti-Stokes Raman scattering) an instrumental spectral resolution of less than 30 MHz can be routinely achieved. It is limited by the convoluted linewidths of the lasers used for excitation, namely a fixed frequency laser and a tunable dye laser. The CARS signal is generated when the frequency difference of the two lasers coincides with a Raman active rovibrational transition in the molecule.
