Abstract

A supersonic molecular beam has been coupled to a Bruker 120 Fourier transform spectrometer having an ultimate resolution of 0.0015cm−1. The chamber is pumped with a Balzers model DIF-320 (12 inch) diffusion pump backed by an Alcatel model 2063C mechanical pump resulting in a net pumping speed of about 5000 l/s at 10−4 Torr. The system is equipped with a heated nozzle source for studies for studies of slightly volatile species. Preliminary work with this setup will be described.
