Abstract
The Raman and infrared spectra of H3CPOCl2, H5C2POCl2, and iso‐H7C3POCl2 have been investigated. Assuming the symmetry C8 for the skeletal structure CPOCl2 in these compounds, the frequencies found can be assigned fully for H3CPOCl2 and H5C2POCl2, and in the lower region in iso‐H7C3POCl2 only in part. The doubling of the P O stretching in H5C2‐ and iso‐H7C3POCl2 can be explained from Fermi interaction with a CH deformation vibration. Of the two possible P‐Cl stretching frequencies only the symmetrical one is of high intensity.Keywords
