Tóm tắt

The isomers of N2F2 have been characterized in the past by their reactivity towards mercury. Investigation of the infrared spectra showed that inactive N2F2 is trans-1,2-difluorodiazine and may be identified by the single strong band centered at 989 cm—1, with PQR structure. Active N2F2 resembles 1,1-difluorodiazine instead of a cis-isomer. This conclusion was reached by considering the mass spectrum, the chemical reactivity, and both the position of the infrared bands and their shapes. 1,1-difluorodiazine may be identified by strong bands at 1524 (PR), 952 (PQR), 896 (PR), and 737 (PQR) cm—1, respectively. Normal coordinate analyses using the Wilson FG-matrix method were performed on both isomers.
