“…The Raman line at 494 cm-' is depolarized and has no infrared counterpart so we have retained this assignment from our earlier work [I]. Koster and Miller [7] suggested the Raman line at 298 cm-' for this NF, twisting mode but this line has a corresponding infrared band and further the Raman line is strongly polarized. Koster and Miller assigned the N-N stretching mode to the Raman line at 719 cm-' rather than the 601 cm-' line.…”

“…We have retained the order vWag > vtwisting > vdeformation for the NF, bending modes on the basis of the conclusions drawn by Harvey and Wilson [9] on the relative frequency order for these motions. These workers arrived at the same order we used for X Y , bending modes Koster and Miller [7] Oskam et al [8] This study (gas)…”

“…There have been two recent infrared studies of tetrafluorohydrazine. Koster and Miller [7] reported the infrared spectrum of the liquid and assigned the N-N stretching mode of the gauche isomer to the infrared and band at 735 cm-l. Oskam et al [8] calculated the expected infrared band contours for the two isomers and J.R.DURIC AND R.W.MACNAMEE compared them to the observed contours. These authors reassigned some of the N-F stretching modes as well as some of the twisting and scissoring motions.…”

The Raman spectrum of gaseous N2F4 at a pressure of 760 torr was recorded with a spectral slit width of 3 cm-l. Ten of the expected eleven fundamentals of the symmetric motions of both the gauche and trans isomers give rise to strongly polarized Raman lines. These new data require a reassignment of some of the fundamentals for both the C2 and C2h conformers. The Raman of the solid at 18K was also recorded. Both conformers were found in the solid even after annealing the sample for 9 hours at a temperature of 101.6K and 3 hours at a temperature of 106.8K. Bands attributable to the gauche isomer became more intense relative to those for the trans isomer after several hours of annealing.
