โœฆ Synopsis

The A' (2) and A( 1 ) states of IBr were detected in a free-jet expansion of l Br in Ar, where they were prepared by ArF laser irradiation. The v"= 0-5 progressions of the D'(2 )*-A' transition, and the v"= 0 and 1 progressions of the ~ ( 1 ),--A ( 1 ) transition were observed and recorded for both ~ 27179Br and ~271StBr. Rotationally resolved excitation spectra were recorded for 31 bands of the D' ,-A' (2), v' ,--v" = 1 progression, and band heads were measured at low resolution for an additional > 220 bands of this system and > 100 bands of the [~,--A transition. Analyses of these spectra yield improved spectroscopic parameters for previously unobserved regions of all four electronic states, including the first characterization of the lowest v levels in the A' and A states.

LIF excitation spectra have been recorded for a family of molecules whose dual fluorescence in solution has been ascribed to twisted intramolecular charge transfer (TICT) state formation, promoted through torsional motion in the initially photoexcited state. To eliminate the influence of solvation,

Fluorescence lifetime measurements were made for the S, origins of a number of jet-cooled indole chromophores having carbonyl-containing substituents bonded directly to the chromophore with no spacing aliphatic carbons. The lifetimes are signiticantly shorter than those of compounds having carbonyl
