A. Durand et al., ON THE B-STATE OF THE ICL MOLECULE - HYPERFINE-STRUCTURE AND HYPERFINE PREDISSOCIATION, Chemical physics, 181(1-2), 1994, pp. 209-216
The vibrational level upsilon' = 2 of the B state of ICl has been stud
ied, using laser excitation and fluorescence detection on a molecular
beam. The hyperfine structure of the lines have been measured and this
data has refined the knowledge of the hyperfine constants of the B st
ate. The relative intensities of the hyperfine components have reveale
d a hyperfine predissociation of these levels and the corresponding hy
perfine predissociation parameter a(upsilon) has been measured. Finall
y, the B state predissociation is discussed in the light of this new i
nformation.
