β¦ Synopsis
The phctoeIectron spectrum has Seen observed using He 584 a excitation.
.rhssignments are made and compared with those for related molecules. . Thiazyl .fluoride, NSF, is isoefectronic with sufphur dioxide SO,. A comparison between the electronic structures of these molecules is of considerable theeretical iriterest since the bonti stretching force constants are well represented by the very different valence-bond formulae NZ&F and O=S=O. Work by Barrow et al. [?,2] on the electronic spectrum of NSF showed that the variations of the geometry on eiectronic excitation from the ground state are at variance with Walsh's rules {3]. It is suspected that in the corresponding SO, transitions [4,p.605],

Thiazyl cyanide, NSCN, has been produced in a flow system by passing thiazyl chloride, NSCI, over heated silver cyanide, AgCN. The He I photoelectron spectrum of NSCN shows prominent bands at 11.33, 13.52, 14.02 and 14.97 eV, in good agreement with ab initio SCF molecular orbital calculations. The f
