Abstract

Interstellar detections of isocyanic acid\footnote{Snyder, L. E. \& Buhl, D. 1972, ApJ, 177, 619.} , methyl isocyanate\footnote{Halfen, D. T., Ilyushin, V. V., \& Ziurys, L. M. 2015, ApJ, 812, L5. Cernicharo, J., Kisiel, Z., Tercero, B., et al. 2016, A\&A, 587, L4.}, and very recently also ethyl isocyanate\footnote{Rodr\'{i}guez-Almeida, L. F., Rivilla, V. M., Jim\'{e}nez-Serra, I., et al. 2021, A\&A, 654, L1.} open the question of the possible detection of the related molecule vinyl isocyanate in the interstellar medium. Similarly, astronomical observations of ketene\footnote{Turner, B. E. 1977, ApJ, 213, L75.} places vinyl ketene among the species of potential interstellar relevance. In the present work, both vinyl species were generated by thermolysis of suitable precursors at $500^{\circ}$C and their room-temperature rotational spectra were recorded between 218 and 330 GHz using the Prague millimeter wave spectrometer\footnote{Kania, P., St\v{r}\'{i}tesk\'{a}, L., \v{S}ime\v{c}kov\'{a}, M., \& \v{S}. Urban. 2006, J. Mol. Struct., 795, 209.}. The spectroscopic measurements and analyses presented here will allow to search for both molecules in the millimeter wave surveys of interstellar sources such as those recorded by Atacama Large Millimeter/submillimeter Array. \vspace{0.5cm} \textbf{Acknowledgments:} L.K., J.K., K.V., K.L., and P.K. acknowledge the financial fundings from the Czech Science Foundation (GACR, grant No.~19-25116Y) and the Ministry of Education, Youth and Sports of the Czech Republic (MSMT, grant No.~8J21FR006).
