Infrared Spectrum of Methyldifluoramine

摘要

The infrared spectra of gaseous CH3NF2and CD3NF2, and of solid CH3NF2have been recorded. They are discussed in terms of the symmetry of Point GroupCs. The unsymmetric methyl vibrations, which are degenerate under the localC3vsymmetry of the group, were found to undergo splitting of smaller magnitude than in analogous compounds ofCsoverhyphen;all symmetry. The two nearly degenerate components of each of these motions appear to be coupled through rotation.
