Abstract
The high-resolution infrared spectrum of the polar N2O dimer has been observed in the region of the N2O ν3 fundamental (â¼1280 cmâ1) using a tunable diode laser to probe a pulsed supersonic slit jet. About 120 rotational transitions were assigned in terms of an a/b hybrid band of a planar asymmetric top molecule with a slipped parallel structure. The vibrational origin was determined to be 1290.21 cmâ1, showing a blue shift of 5.31 cmâ1 with respect to the monomer band origin. In addition, the spectrum of the nonpolar isomer at 1279.71 cmâ1 has been remeasured and analyzed in improved detail. Small but widespread perturbations are noted in this band, which appear somewhat similar to larger effects observed previously in the ν1 + ν3 region for nonpolar (N2O)2.
