The infrared spectrum of the $\nu 2$ band of $CD3I$ near $949cm-1$ has been studied by means of an infrared microwave sldeband laser spectrometer. Frequencies of transitions have been obtained by fitting the spectral lines to a Gaussian lineshape. Quadrupole hypertine spectra have been resolved for several transitions even in the Doppler limit. New molecular constants and the results of an analysis of the Coriolis interaction with the $\nu 2$ state will be presented and compared to previous results.
