Abstract
The $2242-2273 \mbox{cm}^{-1}$ region of the $\nu_{4}$ band in $CD_{3}Br$ has been remeasured at a resolution limit of $0.025 \mbox{cm}^{-1}$. Line assignments have been extended up to $J = 50$ in some sub-bands. Transitions in the $KAK = -8$ sub-band have been assigned, and the perturbation apparent in this region has been analyzed by considering the Coriolis x-y interaction with $\nu_{3}+\nu_{5}^{\pm 1}+\nu_{6}^{\pm 1}$. The Coriolis x-y coupling parameter $W_{xy}$ and the $\nu_{3}+\nu_{5}^{\pm 1}+\nu_{6}^{\pm 1}$ band center $(in \ \mbox{cm}^{-1})$ are 0.1960 and 2339.17 for $CD_{3}^{79}Br$, while the corresponding values for $CD_{3}^{81}Br$ are 0.01956 ad 2337.95.
