โฆ Synopsis
A new photoelectron spectrum has been observed in the pyrolysis products of dimethyldisulphide, CHaSSCH3. As the major product under these conditions is known to be the unstable species thioformaldehyde, H2CS, the new spectrum has been assigned to this molecule. The first ionisation potential is 9.34 -+ 0.01 eV which compares well with the result obtained by other techniques. The evidence for this assignment is discussed.

The inner-valence (20-36 eV) photoelectron spectrum of N, is interpreted by comparing with various spectra (such as absorption, N+-yield, fluorescence-yield, and core-level photoelectron spectra). This comparative study conflrms the previous assignments on the bands at 25.3 and 29.0 eV and clarifies
## Combined photoelectron and microwave techniques have been used to study the unstable species thioacetaldehyde, CHq,CHS, and thioacetone, (CH&CS. These species are produced when their re.spective cyclic trimers, 1,3,5-trimethyl s-trithiane and hexamethyl s-trithiane, are pyrolyzed. The trimer va
Thie letter gives a new interpretation of the highest peaks observed by Edqvist et al. in the photoelectron spect-of NO. This interpretation is based on the fact that if some Mates have anomalous int%msities, they must be represented by mixing with doubly excited coufi~rations and consequently their
