The infrared absorption spectrum of diimide (N2H2) in the 3.2 μm region has been reexamined at higher resolution than previously, and that of dideuterodiimide (N2D2) at 4.3 μm has been recorded for the first time. The ν5 fundamental (A- and B-type hybrid band) for both isotopic molecules has been analyzed, and a complete set of rotational and centrifugal distortion constants for the ground and ν5 = 1 states have been determined. The rotational constants of the ground states are (cm−1) [Formula: see text] and the following geometrical parameters were obtained for the planar trans-conformation of diimide : [Formula: see text] From the intensity alternation observed in the J structure of N2H2 spectrum, it is concluded that diimide has a totally symmetric ground state.
