Stimulated Raman investigation of CO2-laser-excited SF6

Rotationally resolved Raman-optical double resonance with fluorescence detection

A pulsed excitation sequence, consisting of coherent Raman pumping of a molecular rovibrational transition followed by rovibronic probing through visible laser-induced florescence, is used in Raman-optical double resonancestudies of D(2)CO. The experiments demonstrate enhanced sensitivity, with respect to conventional coherent Raman spectroscopy, and enable individual O- and P-branch Raman transitions to be distinguished with high specificity under effectively collision-free conditions.

Optical Stark effects on pure-spin Raman transitions in molecular oxygen

Fully resolved pure-spin Raman transitions near 2 cm(-1) have been observed in (3)Sigma(g) ground-state molecular oxygen using stimulated Raman techniques. Anomalous differences between polarized and depolarized spectra are fully explained in terms of optical Stark effects.
