Amorphous Solid Water (ASW): Pulsed Laser Ablation of ASW/CO2 Thin Films Oscar Rebolledo-Mayoral, Jaimie Stomberg, Stephanie McKean, H. Reisler,* and C. Wittig* Department of Chemistry, University of Southern California, Los Angeles, California 90089, United States ABSTRACT: Thin films composed of 400 500 monolayers (ML) of either amorphous solid water (ASW) or ASW/CO2 mixtures are grown atop a MgO(100) substrate under ultrahigh vacuum conditions. Samples are irradiated at an infrared frequency of 3424 cm 1, which lies within the broad OH stretch band of condensed water. Ablation is achieved using 10 ns pulses whose energy (
