Hydrazine, N/sub 2/H/sub 4/, and its reactions with HF, F/sub 2/, and O/sub 3/ have been studied in an argon matrix. Vibrational assignments have been made for hydrazine, including clarification of the /nu//sub 6/, /nu//sub 10/, and 2/nu//sub 7/ bands. Complexation of N/sub 2/H/sub 4/ with HF produced a strong band at 2928 cm/sup /minus/1/ (/nu//sub s/(HF)) and sharp bands at 940 and 922 cm/sup /minus/1/ (/nu//sub 1/(HF)), as well as several perturbed N/sub 2/H/sub 4/ submolecule absorptions; the frequencies of these bands suggest a chelated structure similar to that for the NH/sub 2/OH-HF complex. Hydrazine and fluorine reacted during deposition to give the NH/sub 2/NHF-HF complex (/nu//sub s/ = 3113 cm/sup /minus/1/, /nu//sub 1/ = 726, 680 cm/sup /minus/1/). Reaction of hydrazine and ozone produced hydroxyhydrazine, NH/sub 2/NHOH, and minor products during deposition; photolysis increased the yield of hydroxyhydrazine. Evidence for an intramolecular hydrogen bond was found for NH/sub 2/NHOH. This matrix study presents the first spectroscopic evidence for both NH/sub 2/NHF and NH/sub 2/NHOH. 32 references, 3 figures, 4 tables.
