Hydrogen Bonded

The hydrogen bonded heterodimer formed between oxirane and hydrogen fluoride has been identified through its infrared and microwave spectra. Rotational constants/MHz and centrifugal distortion constants/kHz for the following isotopic varieties have been derived from an analysis of the rotational spectra in the vibrational ground state: A B A (CH 2 ) 2 160* • -HF 16099 3638.75 3462.31 15.3 25.8 (CH2)2160- • *DF 15984 3605.66 3434.85 14.1 20.9 For the species (CH2)2180 • • • HF only the rotational constants 7059.7 MHz and B — C = 135 MHz could be obtained. It is established from arguments based on Pband A that the dimer has a pyramidal configuration at the oxygen atom and that the molecular point group is (7g. If the justifiable assumption is made that the monomer geometries are unchanged on dimer formation, then the observed rotational constants for (CH 2 )2160* • -H F leadtor0(O* • *F) = 2.627 A ja n d ^ = 71.8°, where ^ is the angle between the plane of the three-membered ring and the H—F direction. Replacement of H by D in the hydrogen bond does not significantly change these values.

Hydroxyl stretching frequency data upon 1-dimethylamino-3,3-diphenylhexan-4-ol and related amino-alcohols are reported which give evidence of unusually strong intramolecular hydrogen bonding between the hydroxy and t-amino functions of these compounds. In corresponding salts, concentration independent vOH bands, typical of hydrogen bonded species, also occur and a bonded system comprising anion, OH, and N+H functions is proposed together with probable methadol base and salt conformations.
