Spectroscopic studies of diatomic noble gas halides: Analysis of spontaneous and stimulated emission from XeCl
Abstract
A XeCl emission band system with peak intensity near 3080 Å is reported and analyzed. The vibrational analysis of this spectrum includes 24 violet-degraded bands assigned to Xe35Cl and Xe37Cl, and yields (for Xe35Cl) ΔTe=32 405 cm-1, ωe'=195.2 cm-1, ωe″=26.3 cm-1, and De″=255 cm-1. The weakly bound 2Σ+ ground state of XeCl resembles a van der Waals state, whereas the excited state is the analog of the CsCl ground state. Approximate potential curves are derived for these XeCl states. Lasing is observed on the 0-1, 0-2, and 0-3 bands of this transition, with a peak output power of 1.5×104 W.
