Abstract
The infrared spectrum of a sample of natural monobromoacetylene (HCCBr ) has been recorded with the Bruker IFS 120 Fourier spectrometer in th e wavenumber region 1100-9800 cm(-1) with a resolution close to the Do ppler limit. The 2v(4), v(1), 2v(1), and 3v(1) band systems have been analyzed. Altogether, 24 vibrational bands belonging to the (HCCBr)-Br -79 and 26 bands belonging to the (HCCBr)-Br-81 isotopic species have been observed and rotationally assigned. An anharmonic resonance model based on rectilinear normal coordinate theory has been used to produc e the vibrational assignments for the observed bands. (C) 1995 Academi c Press, Inc.
