✦ Synopsis

In the range 110-200 nm the absorption features of Si#& closely resemble those of SiCl, and the peaks observed are tentatively assigned to the Rydberg transitions of a Cl lone-pair electron. Two diffuse bands in the SiF,CH3 absorption are also assigned to Rydberg excitations. The spectrum of GeF., shows a broad band considered to be a valence excitation of the outermost orbital. The emission of the SiClz (A'B, -tg'A,) transition was found in the photoexcitation of Si2C16.
