Study of nascent NaH in sodium-hydrogen mixture using resonant CARS and FWM processes

Abstract

The Coherent anti-Stokes Raman Spectroscopy (CARS) technique was applied to measure the O Q, and S branches from the first, second and third overtones of the XICt ground state of NaH. Moreover, P and R doublets were also measured when the anti-Stokes signal was rcsonant with some lines of the electronic transition AIC+- XIC+ of NaH. The high sensitivity resulting from pump laser resonances allowed us to study the Na(nl)+H2 -i NaH+H reaction dynarnics.
