Abstract
Progress is reported in the analysis of CH and CD stretching overtones and their accompanying Fermi resonances in C2H4, C2H3D, CH2CD2 and C2HD3. CH stretching overtone data have been obtained for a number of partially deuterated alkanes, halogenated alkanes, MeCN, MeC2H, MeNH2, Me2NH, MeOH and Me2O. Values of anharmonicity constants xii obtained from these are compared with the results of local-mode studies. A provisional Fermi resonance analysis of CH(CD3)3 is reported. The possiblity of a relationship between xii, ωi and CH dissociation energy is explored.Keywords
