Polarization-sensitive resonance coherent anti-Stokes Raman scattering spectroscopy of magnesium octaethylporphine (MgOEP) in dichloromethane is reported. The measurements were performed in resonance with the Q-band electronic absorption where linear resonance Raman spectroscopic measurements were f

β¦ Synopsis
CARS experunents on s-tetratme vapour show that the elecuonic resonance enhancement in the Q-branch is most effec nre for the lower J values This suggests that the radiationless relxxauon rate III the excited state mcreases with rotational quantum number Delayed prcosecond CARS experiments mdrcate that the rotation-vibration couplung for the 1008 cm-' pound-state vlbratlonal mode IS approvunately 2 MHz.

Transient CARS spectroscopy has been used to study the Raman-active vI (symmetric C-D stretch) vibration-rotation band of CD, radicals formed by gas phase laser photolysis of azomethane-d,. The following spectroscopic constants have been deduced: bandorigin=2157.5cm-',~=-0.026cm-',AC=-0.018cm-~,and
## Abstract Sulphur vapour was investigated by Raman spectroscopy using six laser excitation wavelengths located in the electronic absorption band of the S~3~ molecule (406.7β514.5 nm). With excitation wavelengths close to the S~3~ Ξ»~max~ (395 nm) the spectra are mainly resonance enhanced. With the
## Abstract New possibilities for the resolution of Raman bands, provided by polarizationβsensitive CARS in combination with a phaseβmismatching technique, are presented. The use of this combination of techniques allows one to achieve the most informative spectra and resolve the complex structure o
