✦ Synopsis

The 2 31-I-X 31-I electronic band system of the aluminum dimer has been measured with the CRLAS technique. While several vibronic bands were examined under high resolution, no rotational features could be discerned. Band contours imply a rapid (r < 10 ps) predissociation in the upper state, explaining why this band system was not observed in previous R2PI and LIF studies. The upper electronic state was determined to have a vibrational frequency of 210 + 4 cm-x.

A laser-induced-fluorescence (LIF) investigation of the jet-cooled dimer of the aromatic molecule N-ethylcarbazole is presented. The dimer behaves essentially as a perturbed monomer. The origin is shifted bathochromically some 606.8 cm-' relative to that of the monomer, and this can be explained in

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.
