Abstract
The upper component of the ground state perpendicular tunneling-rotation spectrum of the $Ar-H_{2}O$ dimer has been observed near $21cm^{-1}$ using a cw planar supersonic jet and a tunable far infrared laser system. Analysis of this sub-band suggest an A rotational constant less than $17 cm^{-1}$ and a tunneling splitting of $2-11 cm^{-1}$. Observation of one sub-band of the out-of-plane bending vibration, $(1 K_{a}-0 \rightarrow 0 K_{a}=1)$ near $24 cm^{-1}$ goves a bending vibration near $40 cm^{-1}$. The data is used to suggest the structure of the intermolecular potential energy surface.
