Complete characterization of the (D2O)2 ground state: High Ka rotation–tunneling levels

Abstract

We report the observation of extensive a- and c-type rotation–tunneling (RT) spectra of (D2O)2 for Ka = 0–4. These data allow quantification of molecular constants and tunneling splittings for a number of previously unobserved RT states of (D2O)2. The vibrational ground state has thus been characterized to energies as high as those of some of the intermolecular vibrations, and we present the first test of the VRT(ASP-W) potential at these high Ka states.
