论文摘要
甲基乙烯基酮（C $ _4 $ h $ _6 $ o）是一种在大气化学中重要的，不稳定的有机化合物。我们制备了甲基乙烯基酮的分子束，旋转温度为1.2（2）〜k，并证明了\ emph {s-cis}和\ emph {s-trans}甲基乙烯基酮的空间分离，使用静电脱位器。所得的样品密度为$ 1.5（2）\ times10^{8}〜\ text {cm}^{ - 3} $，用于激光电离区域中的直接光束。这些构象体选择的甲基乙烯基酮样品非常适合特异性化学反应性研究，例如在Diels-Alder-Alder Cycloadition反应中。
Methyl vinyl ketone (C$_4$H$_6$O) is a volatile, labile organic compound of importance in atmospheric chemistry. We prepared a molecular beam of methyl vinyl ketone with a rotational temperature of 1.2(2)~K and demonstrated the spatial separation of the \emph{s-cis} and \emph{s-trans} conformers of methyl vinyl ketone using the electrostatic deflector. The resulting sample density was $1.5(2)\times10^{8}~\text{cm}^{-3}$ for the direct beam in the laser ionization region. These conformer-selected methyl vinyl ketone samples are well suited for conformer-specific chemical reactivity studies such as in Diels-Alder cycloaddition reactions.
