Abstract
Using the DFWM technique we determined rotational and vibrational temperatures of NaH molecules in a dynamical system consisting of NaH, Na, H and H2 for several heat-pipe oven temperatures. We applied a new way to determine the dependence of the DFWM signalI c int on the power of the transition dipole momentµ without previous knowledge of the temperature. The revealed dependence isI c int αµ4. In this case the laser intensities were found to be of the same order as the saturation intensity in accordance with simple DFWM theory. A usual Boltzmann plot was employed for the determination of the relevant rotational temperatures, which displayed higher values than the oven temperature.
