Abstract

Much attention has surrounded 1,3-butadiene because this conjugated diene, the simplest of all, is an ideal candidate to observe the effects of $\pi$-electron delocalization, and because the species is of central importance in a wide range of chemistry applications. Butadiene exists in two forms, the most stable planar \textit{trans} and the long-elusive \textit{gauche} lying 12 kJ/mol higher in energy. The later was only conclusively detected in the gas phase by some of us recently, in a work that allowed the determination of a partial structure from a combination of pure rotational measurements and high level quantum chemical calculations. In an attempt to detect the ro-vibrational spectrum of \textit{gauche}-butadiene, we have re-investigated the far-infrared spectrum of the species at both the SOLEIL synchrotron facility and the Canadian light source using three experimental set-ups allowing to reach rotational temperatures ranging from 30 to 350 K. We will present our results on new fundamentals of the \textit{trans} form, and on the \textit{gauche} form.
