Abstract

The Fourier-transform absorption spectrum of nitrosobenzene vapour in the near-infrared has been recorded, and the vibrational bands near the 869 nm electronic origin of the A¹A? ? X¯¹A' (n,p^*) transition have been re-analysed. The prominent torsional structure observed is shown to represent sequence transitions in the torsional mode. Electronic excitation leads to an increase of the V₂ barrier hindering internal rotation from roughly 1300 cm^-1 in the ground to 2500 cm^-1 in the (n,p^*) excited state. © 1985.
