Abstract

Vinyl alcohol can exist in two rotameric forms, known as \textit{syn}- and \textit{anti}- vinyl alcohol, where \textit{syn} is the most stable. Both rotamers have been observed in the interstellar medium towards Sagittarius B2(N) making them of particular astrophysical importance\footnote{B. E. Turner, A. J. Apponi, ApJ 561, 207 (2001)}. Vinyl alcohol has been subject to various spectroscopic investigations, however, the \textit{anti} rotamer has only been obsvered in the microwave region\footnote{M. Rodler, J. Mol. Spec. 114, 23 (1985)}. We report the high resolution (0.001 \wn) FTIR spectrum of \textit{anti}-vinyl alcohol collected at the infrared beamline facility of the Australian Synchrotron. Vinyl alcohol was produced via the pyrolysis of 2-chloroethanol at $900^{\circ}$C\footnote{D-L Joo, et al., J. Mol. Spec. 197, 68 (1999)}, and its far infrared spectrum reveals the presence of the strong \nub{15} fundamental and hot band of \textit{anti}-vinyl alcohol. Rotational and centrifugal distortion constants of this higher energy rotamer have since been determined for the \nub{15} and 2\nub{15} states, and the ground state constants have been refined.
