INFRARED SPECTRUM OF DIFLUORAMINE

Author Institution: Molecular Spectroscopy Section, National Bureau of StandardsThe infrared spectrum of gaseous difluoramine, $HNF_{2}$, has been investigated over the range $250-4000 cm^{-1}$. The fundamental frequencies (in $cm^{-1}$), their assignment and band types are as follows: $3193, \nu_{1}(a^{\prime}$, type C); 1306, $\nu_{2}(a^{\prime}$, type B); 972, $\nu_{3}(a^{\prime}$, type B); $500, \nu_{4}(a^{\prime}$, type B); $1424, \nu_{5}(a^{\prime\prime}$, type A); $888, \nu_{6}(a^{\prime\prime}$, type A). the three type-B bands are well resolved into Q branches with a spacing of approximately $3 cm^{-1}$.The P and R branches of the type A $888 cm^{-1}$ band are also resolved with a spacing of approximately $0.7 cm^{-1}$. The values of the rotational constants A and ${^{1}}/_{2} (B+C)$ obtained from these infrared results are in agreement with those determined much more precisely from the microwave spectrum. No inversion splitting was detected in the fine-structure of the resolved bands
