Raman Spectra and Potential Constants for CF3Cl, CF3Br, and CF3I

摘要

Raman frequencies have been obtained for gaseous CF3Cl and CF3Br and for liquid CF3I at mdash;40deg;C. The assignments are in agreement with previous investigations. The spectra have been analyzed using a simplified, sixhyphen;constant potential function of the Ureyhyphen;Bradley type without the assumption of tetrahedral angles around the central carbon atom. In all three cases, it was found possible to reproduce the experimental frequencies to within less than their experimental error.
