| Abstract: | Abstract The infrared spectrum of acetonitrile vapour has been obtained in the range below 100 cm?1. There is an absorption band located at 78 cm?1 which is assigned to overlapping intermolecular vibrations of dimer molecules in equilibrium with the monomer species. The equilibrium constant calculated from the pressure dependence of the band intensity amounts to 42 ± 26 1·mol?1. |
