The 15N multiplet splitting positively identifies absorptions of photolysis products as those of trans‐N2H2 (at 1286 cm−1), trans‐HNND (at 1481 and 1058 cm−1), trans‐N2D2 (at 946 cm−1), and cis‐N2H2 (at 3074 and 1279 cm−1). The spectrum of trans‐N2H2 is in agreement with a planar symmetric structure and the vibrational frequencies are quite close to corresponding vibrations of ethylene.Imidogen, NH, was also observed in both solid argon and in solid nitrogen as another photolysis product. The 15N splitting in the ammonia absorptions shows that the ammonia dimer in solid nitrogen has a cyclic structure.

A dimer band at 387 cm−1, assigned to the torsional distortion of the hydrogen bond, indicates the dimer has an open, not a cyclic structure. The hydrogen bond bending force constant is 0.09 mdyn/A. The hydrogen bond frequency shift in the N–H stretching mode is 150 cm−1, which, by comparison to similar systems, suggests a hydrogen bond energy of about 2 kcal/mole.The infrared spectrum of monomeric HN3 casts doubt upon the earlier gas‐phase assignment of ν6. According to the matrix spectrum, the band center is more likely to be near 588 cm−1.
