✦ Synopsis

Several coumanns, both with "free" and "ng~d~zed" amino groups, wcrc W&cd by c\atat~on spectroscopy m a supr-SOW evpwslon of argon. The lowest nbromc band for the ITIT* electronrc cxckxllon was found to bc dlsplaccd by several hundred cm-l to the blue from the symmcfrlc pos~uon bclween Lhc corrrsponding hot vdpour absorption and cmlsslon bands, suggcswlg a ncgbBblc Franck-Condon overlap for the 00 tranWon.

We report the CH-stretching overtone spectrum of jet-cooled methane in the visible range. Due to the very weak intensity of the transition, the intracavity-laser-absorption-spectroscopy technique (ICLAS) was used with a free jet of methane from a slit orifice placed inside a dye-laser cavity.

The (0,0) and (1,0) bands of the E 3 -X 3 transition of TiO in the near-infrared have been recorded by frequency modulated laser absorption spectroscopy in a laser ablation/free jet expansion source. The observed linewidths (FWHM) varied from 300 to 500 MHz according to the expansion conditions and
