- Abstract
- Infrared spectrum of the weakly-bound CO2-C2H 2 complex in the region of the CO2 ν3 fundamental band (∼2349 cm-1) is observed in a pulsed supersonic slit jet expansion using a tunable diode laser probe. Two bands are observed and analyzed: the fundamental (C-O asymmetric stretch) and a combination involving the intermolecular torsional (out-of-plane bend) vibration. The resulting torsional frequency is 44.385(10) cm-1. This represents the first observation of an intermolecular frequency for carbon dioxide-acetylene complex. A comparison between the results obtained here and those previously reported for N2O-C2H2 complex is discussed.
