Abstract: The infrared spectrum of the $X^{2}\Pi$ state of CBr from 680 - 750 $cm^{-}1$ has been measured using diode laser absorption spectroscopy. The CBr radicals were produced by 193 nm excimer photolysis of bromoform. Transitions belonging to the $v = 1 \leftarrow 0,2 \leftarrow 1,3 \leftarrow 2$ and $4 \leftarrow 3$ bands of both isotopomers, $C^{79}$Br and $C^{81}$Br have been identified. Employing {case}(a) matrix elements, spectroscopic parameters were obtained from a least squares fit where the transition frequencies of both isotopomers were fitted simultaneously. The results were used to obtain a Rydberg-Klein-Rees (RKR) potential. Additionally, the kinetics of the CBr + $O_{2}$ reaction were investigated. This is first recording of vibrational spectra of CBr.
