The spectra of the A X transition of the NO X molecular complexes, where X = N₂, CO and CH₄, have been recorded using one-color (1+1) REMPI spectroscopy. The spectra exhibit vibronic features, which are interpreted as hindered internal rotation and the underlying end-over-end rotational structure. Some insights into the structure of the spectra are gleaned from ab initio calculations.
