Abstract | Infrared spectra of a new planar isomer of the OCS-(C2H 2)2 trimer are observed in the region of the OCS ν1 fundamental band (∼2060 cm-1) using a tunable diode laser to probe a pulsed supersonic slit jet expansion. Three isotopologues are analyzed in detail (16OCS-(HCCH)2, 16OCS-(DCCD)2, and 18OCS-(DCCD)2), while the spectrum of a fourth is found to be heavily perturbed ( 18OCS-(HCCH)2). Observed rotational constants of planar OCS-(C2H2)2 agree fairly well with previous ab initio calculations, and with previous and present semi-empirical calculations. It should now be possible to assign the microwave spectrum of planar OCS-(C 2H2)2. © 2011 Elsevier B.V. All rights reserved. |
