Abstract
The infrared dissociation spectra of several halogenated methanes (CHCl2F, CH3F, CF3I and CF3Br) have been studied. Bonded and free C–F stretch excitations have been observed.H-bridges forming the bonding in CHCl2F or CH3F dimers lead to very large red-shifts in the dissociation spectrum with respect to the gas-phase absorptions. Double resonance techniques have been employed to study the homogeneity of the spectral features.
