Abstract
Vinyl acetate (C$_4$H$_6$O$_2$) was isolated in matrices of nitrogen, argon, and krypton. The ultraviolet irradiation ($\lambda$$<$ 250 nm) of the matrix results in the formation of a number of products including carbon dioxide, carbon monoxide and ketene (CH$_2$CO). Irradiation of the vinyl-$^{13}$C$_2$ labeled compound yields a mixture of labeled and unlabeled CH$_2$CO, CO$_2$ and CO, indicating that these products arise from the acetyl and the vinoxy moieties. The product $^{12}$C/$^{13}$C ratios vary with matrix (N$_2$$>$Ar$>$Kr). The photolysis efficiency is reduced when the parent compound is deuterated.
