Abstract

1-Arsabutadiyne (2-propynylidynearsine, HC3As), is efficiently produced by photolysis of propynylarsine isolated in solid argon. The observed infrared absorption spectra and predicted molecular parameters of HC3As and HC3P show significant similarities, but large differences compared to HC3N.
