The authors have measured the far-infrared vibration-rotation-tunneling (VRT) spectrum of an intermolecular vibration of (D{sub 2}O){sub 2} near 68 cm{sup -1}. In addition, further transitions of the VRT band of (D{sub 2}O){sub 2} previously reported by Pugliano et al. have been observed. By considering symmetry restraints on the selection rules, these bands have been assigned to the out-of-plane H-bond torsional and in-plane acceptor wagging modes predicted by many theoretical calculations. The experimental-theoretical discrepancy in the measured frequencies of these bands indicates the importance of a fully coupled six-dimensional calculation of the dynamics for the water dimer.
