✦ Synopsis

The Fourier-transform nbsorplion spcr~rurn of nilrosobrnzene vapour in the near-infrared has been recorded. and Ihe vibraGonal bands near the 869 nm electronic origin of the .&,'A" + R 'A' (n.sr-) Iransilion have been re-analysed. The prorninrrn~ torsional s~mc~ure observed is shown IO represent sequence lransilions in the torsional mode. Electronic exciralion leads to an increase of Ihe V, barrier hindering inlemal rokxion from roughly 1300 cm-' in the giound 10 1500 cm-' in Ihe (n,#) excited stale.

Dispersed and Fourier-transform spectra of NCNO vapour have been measured and some of the vibrational and cozrse rotational structure has been analysed. The absorption is due to a 'A" .-1 A'(n\_,a\*) transition with the origin at 6522 nm. The main geometry change accompanying the transition consists
