Automated high-resolution CARS spectrometer and coherent spectroscopy of the Raman scattering by tetrahedral molecules
A description is given of a spectrometer for coherent anti-Stokes Raman scattering (CARS) with an instrumental resolution of ~ 10−3 cm−1 and an automated data acquisition and processing system. The results are given of CARS investigations of the rotational structure of the vibrational state ν1(a1) of the spherical-top molecules CH4 and CD4.
