Spectra of the ν = 5 and ν = 6 levels of the CH stretch in CHBr3 have been recorded via in-cavity dye laser photoacoustic spectroscopy. Linewidths for these absorptions have been determined and are discussed in light of existing theory and results on the linewidths of the corresponding transitions in CHCl3. When data on the fundamental are combined with ν = 5 and ν = 6 data it is possible to determine values for the local mode harmonic frequency and anharmonicity. Absolute absorption cross sections for the ν = 5 and ν = 6 levels are reported.
