Scientific paper

Spectra of the weakly-bound N_{2}O-C_2H_2 and N_{2}O-C_2D_2 complexes in the region of the N_{2}O ν_{1} fundamental band ( 2224 cm^{-1}) are observed in a pulsed supersonic slit jet expansion probed with a tunable diode laser. Two bands are analyzed for each complex: the fundamental (N-N stretch), and a combination involving the intermolecular torsional (out-of-plane bend) vibration. The resulting torsional frequencies are 44.37 and 40.01 cm^{-1} for the C_2H_2 and C_2D_2 complexes, respectively. This represents the first observation of the N_{2}O-C_2D_2 isotopomer, and the first direct determination of an intermolecular frequency for nitrous oxide - acetylene.
