✦ Synopsis

High-resolution vibration-rotation spectra of a sample of natural monobromoacetylene ( (\mathrm{HCCBr}) ) have been recorded with the Bruker IFS 120 Fourier spectrometer in the region of the bending and (\mathrm{CBr}) stretching fundamentals. Altogether 23 bands belonging to (\mathrm{HCC}^{79} \mathrm{Br}) and 23 bands belonging to (\mathrm{HCC}^{81} \mathrm{Br}) isotopic species have been analyzed rotationally, yielding accurate vibrational term values and rotational constants. Coriolis-, rotational (l-), and Fermi-resonance interactions have been observed and analyzed in some of the bands. (c) 1994 Academic Press, Inc.
