Abstract
A pulsed excitation sequence, consisting of coherent Raman pumping of a molecular rovibrational transition followed by rovibronic probing through visible laser-induced fluorescence, is used in Raman-optical double resonance studies of D2CO. 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.
