We present the experimental demonstration of a novel, efficient, and vibrational selective technique to prepare population in vibrational level v '' = 1 using the stimulated Raman pumping. Photoacoustic Raman signal has been studied in non-radiative transitions in the molecule H-2 (v' = 0) and (v' = 1). The population fraction in the v '' = 1 level can be estimated by using combined photoacoustic Raman spectroscopy with stimulated Raman pumping for the first time.
