title: Pulsed supersonic molecular-beam coherent anti-Stokes Raman spectroscopy of C(2)H(2).
abstract: We have obtained a high-resolution coherent anti-Stokes Raman spectrum of C(2)H(2) in a pulsed molecular beam and have used the resolved Q-branch spectrum to study the properties of the expansion. Cluster formation limited the minimum observed rotational temperature in the pure-acetylene expansion to 30 K.
