The infrared spectrum of N2H2 in the 3.1 μ region and the ultraviolet spectra of N2H2 and N2D2 have been examined. The analysis of the infrared spectrum indicates that N2H2 in the ground state has a planar trans-conformation with with rN−N = 1.238 ± 0.007 Å and [Formula: see text], assuming rN−H to be between 1.05 and 1.08 Å. In the vacuum ultraviolet spectrum near 1700 Å, progressions of bands with spacings of 1180 and 950 cm−1 have been observed for N2H2 and N2D2, respectively. From the intensity alternation in the J structure of the vacuum ultraviolet spectrum it seems to follow that the electronic ground state of N2H2 is not totally symmetric.

Absorption Bands

A number of new absorption bands have been found in the vacuum ultraviolet spectrum of O2 that has been excited by a discharge. The lower states of these bands are the [Formula: see text] and a1Δg states. The analysis of the bands, together with some newly analyzed bands arising from ground-state O2, has allowed us to identify four new electronic states. It has not been possible to assign these states to particular electron configurations of O2.
