| Abstract: | The ir spectra of 2-halogenated ethanols have been studied. A frequency assignment shows that the chloro, bromo and iodo derivatives exist as rotational isomers with the gauche conformer being the more stable due to an internal hydrogen bond. This internal hydrogen bond stabilizes the gauche form of the fluoro derivative to such an extent that there is no conclusive evidence for the occurrence of a trans form. |
