Phys. Rev. Lett. 57, 2920–2923 (1986)Spectroscopic Observation of Phase Coexistence in SF6-Arn Clusters for n=10-20Received 14 July 1986; published in the issue dated 8 December 1986 In infrared photodepletion spectroscopy of molecular beams of SF6-Arn clusters, a shifting and broadening of the ν3 band of SF6 was observed by Gough, Knight, and Scoles for a narrow range of experimental conditions. A Monte Carlo simulation of those spectra based on an instantaneous dipoleinduced dipole model reproduces them semiquantitatively and shows that such broadening can be caused by phase coexistence. However, cluster-size distribution effects make it nuclear whether this is the source of the broadening observed in the existing data. © 1986 The American Physical Society URL:
