The \documentclass{article}\pagestyle{empty}\begin{document}$ {}^3\sum\nolimits_{\rm u}^ - {} \leftarrow {}^3\sum\nolimits_{\rm g}^ - {} $\end{document} transitions are investigated of sulphur dimers, matrix‐isolated in Ar and Kr. Each vibrational subband of the electronic absorption appears to consist of several superimposed narrow bands. The separation between the narrow bands is determined to be 60 cm −1 in Ar and 50 cm −1 in Kr. The complex structure is interpreted to be caused by phonons of the matrix materials. The potential parameters of sulphur dimers in Ar and Kr are also calculated.
