Formly chloride is an unstable compound with a half life of approximately 30 minutes. The molecule has been observed in the reaction of ozone with chlorinated hydrocarbons. In this study, formyl chloride was prepared by the method of Takeo and $Matsumura,1$ in which formic acid was passed over $PCl5$ at room temperature. Based upon low resolution $studies,2$ the $v6$ band at $932.3cm-1$ (H-C out-of-plane bend) should be perturbed, presumably by a coriolis interaction with with the $v4$ fundamental (C-Cl stretch) which is a very intense perpendicular band at 739 $cm-1$. The $v6$ band, which is a pure C-type band, is very weak and lends itself to study under the high S/N of the diode laser. The results of the analysis and assignment will be $discussed.1$H.
