Abstract

A qualitative description of cooling molecules in a pulsed supersonic jet is given on the basis of literature data. Procedure of measurements is described and known relations are presented which allow one to determine the rotational temperature and concentrations of molecules in a jet using the measured intensities of IR absorption lines. The parameters of SF₆ and NH₃ jets have been determined for various pulsed valves by means of tunable diode lasers.
