Abstract

An efficient vibrationally selective technique to build-up the v″ = 1 vibrational levels in gaseous hydrogen is demonstrated using stimulated Raman pumping (SRP). Both photo-acoustic Raman spectroscopy (PARS) and coherent anti-Stokes Raman spectroscopy (CARS) are used to study non-radiative and radiative (v″ = 0 and v″ = 1) transitions in gaseous H2 molecules. The population fraction in the v″ = 1 vibrational level has been estimated using combined photo-acoustic and coherent anti-Stokes Raman spectroscopy with stimulated Raman pumping. © 2011 Elsevier B.V.
