Abstract

Abstract: Gas-phase infrared spectra of the unstable phosphaalkenes CF2= PH, CF2= PCF3, and CH,= PCI and their deuteriated species have been measured and vibrational assignments have been made. The C= P stretching bands are observed at 1349.5, 1350.2, and 1365.3 cm-'for CF2= PH, CF2= PD, and CF2= PCF3, respectively, and at 979.7 and 847.9 cm-I for CH,= PCI and CD,= PCI, respectively. Normal coordinates were treated for ...
