✦ Synopsis

The absorption spectrum of the yttrium monochloride molecule (YCl) produced in a King-type furnace has been recorded at high resolution using a 5-m Fastie spectrograph. A new band system in the UV region (centered at 3291 A ˚) has been found and rotationally analyzed. The transition has been assigned to K 1 P-X 1 S / , in accordance with the labeling of the YCl electronic states by Langhoff et al. (J. Chem. Phys. 89, 396-407, 1988) in their theoretical work. Molecular constants for the new state are presented.
