Abstract
The Raman and infrared spectra of ketene $(H_{2}C = CO)$ had been investigated by several authors. While there has been general agreement as to the assignments of the fundamentals in the 1100-32000 $K$ region (K = Kayser = Wave/cm), considerable difficulty has been experienced in the interpretation of the spectrum in the $500-1100 K$ region. In order to provide a correct assignment of the fundamentals for the molecule, a normal coordinate treatment using the Wilson {\bf FG} matrix method has been carried out in the present investigation. The correct assignments are $a_{1}$: 1120, 1390, 2150, 3060; $b_{1}$: 545, 942, 3160; and $b_{2}$; 588, 916. The calculation of the rotational distortion constants for ketene and of the wave numbers for $D_{2} C$ = CO and HDC = CO are nearly completed.
