Abstract
THE purpose of this note is to record new spectroscopic data for the molecules SiS, SiSe and SiTe. These are members of a group of twenty molecules formed from Group IV and Group VI elements, each of which (with the single exception of CTe) has been shown by earlier work1 to give rise to at least one strong ultra-violet band-system, generally appearing readily in emission. Many of these systems have also been observed in absorption: it is convenient to call them D—X systems. The existence of weaker E—X systems, lying to shorter wave-lengths than the D—X systems of GeS, SnO, SnS, SnSe and SnTe1,2 suggested that other members of the group should possess similar E states.
