Notes:
E±2 symmetry states for K=0, 1 of (H2O)2 are found to be perturbed and a Coriolis resonance model is used to give a satisfactory treatment of the observations. The effective b-type Coriolis coupling constant ζ is 1409.4 MHz, implying appreciable vibrational angular momentum since ζ/2C≈1/8. The spacing Δ between the upper K=0 levels and the lower K=1 levels is 10 719 MHz. The rotational constants from the deperturbation analysis are now found to be in substantially better agreement with those from tunneling states of other symmetries and with the structure of the dimer. The Stark effects of the perturbed states have been analyzed. The a component of the electric dipole moment is well determined; the c component appears to be small, but the results are not completely consistent.
