Abstract

The fluorescence excitation spectrum of XeF cooled in a supersonic expansion with helium has been observed for the wavelength region 2860 to 3205 Å. The cold spectrum displays well-resolved rotational structure for seven of the XeF isotopic species. Analysis of this rotational structure is reported for v′=16–21 in the ? (Ω=1/2) state and for v=0 and 1 in the ? 2Σ+ state. Vibrational intervals have been measured for individual XeF isotopes with an accuracy of ±0.50 cm−1 for vibrational levels v′=11–22 and ±0.37 cm−1 for v=0–2.
