Existence and molecular properties of a gas-phase, hydrogen-bonded complex between hydrogen fluoride and water established from microwave spectroscopy
Abstract
The rotational spectrum of the hydrogen-bonded complex H2O … HF has been analysed to give rotational constants, approximate v= 1 â†� 0 separations for the three lowest-lying vibrational modes, the O … F internuclear distance 2·68 ± 0·01 Å, and a value for the dipole moment component µa of 3·82 ± 0·02 D.
