Abstract
The quenching effect of anharmonicity on the inter-bond coupling and C oriolis interaction is studied. The local to normal mode correlation d iagrams for XY2 and XY3 stretching overtones up to nu = 60 and 20, res pectively, are calculated in the normal mode model with Darling-Dennis on resonances included. The results show that the high-energy stretchi ng vibrations tend to be bond-localized owing to the anharmonic (Darli ng-Dennison) resonances.
