摘要：

The far-infrared laser vibration-rotation-tunneling (FIR-VRT) spectrum of the propane-water complex has been measured in the range 18-22 cm-1. A C-type VRT band has been assigned with a band origin of 19.6 cm-1. The data support the ''kite-shaped'' structure determined from microwave spectroscopy in the accompanying paper, and indicate that the observed VRT band corresponds to torsional motion of the free water proton about the hydrogen bond. This motion is impeded by a barrier that is less than 5 cm-1. We describe our modification of the supersonic slit-jet source designed to permit Stark effects to be measured, and have used second-order Stark shifts to help assign the perpendicular transition observed.
