Abstract The rotational spectra of GeS and GeSe were measured in the frequency range of 66 GHz to 110 GHz with high precision. The breakdown of the Born-Oppenheimer approximation was observed for the rotational constant yol. With the known molecular 37-factor and the electric dipole moment the adiabatic part of the Born-Oppenheimer correction can be extracted from the primary observa-tion on y01. The adiabatic correction is very similar in both molecules but differs from the results in the earlier measurements on PbS.

Van Der Waals Complex

The molecular symmetry group of the Van der Waals complex (H2)2 or (D2)2 is a group of order 16 called G16. This group is used to symmetry label the rotation–vibration states and the nuclear spin states of the complexes; the nuclear spin statistical weights are also determined. The group is used to classify the terms in the expansion of the dipole moment function and to determine the symmetry restrictions for allowed electric dipole transitions. The complex H2–D2 has a molecular symmetry group of order 8, G8, and (HD)2 a group of order 4, G4; the energy level symmetries, statistical weights, and selection rules for these complexes are also determined.

The microwave rotational spectra of the isotopic species H 2 18 0 • • • H 19 F, H 2180 • • • H 19 F, HD 16 0 • •. HF, D 2 16 0 • • • DF and D 2 18 0 • • • DF of the hydrogen bonded heterodimer formed between water and hydrogen fluoride have been observed and analysed to give rotational constants. Evidence from the effects of nuclear spin statistical weights in the spectra leads to the conclusion that the dimer H 20 • • • HF is either planar with C2V symmetry or pyramidal with Cg symmetry but with a low barrier to inversion of the configuration at oxygen. r0-values of the heavy atom distance 0 * • • F have been derived from the observed rotational constants, the value for H 2160 • • • H 19 F being 2.662 Aj. The measured values of electric dipole moment in the vibrational ground state and in the state having v^{0) = 1 are 4.07 and 3.80 D respectively. These values show that excitation of the out-of-plane hydrogen bonding bending mode vP(0) leads to a large decrease in the dipole moment.
