Rotational state-selection with E-species transitions (3_0← 3_{-1},2_0← 3_1,1_0← 1_1) is employed to record the infrared spectra in the range 2750-2900 cm^{-1}. The observed spectra of CH_3OD contain only one vibrational band origin whereas 12 interacting vibrational bands of CH_3OH are observed in the same interval. There are no interacting vibrational bands in the CH_3OD spectra because the first tier states are shifted out of resonance. This observation confirms that the dominant coupling pathway in the ν _3 CH stretch of CH_3OH is the third order coupling of the CH stretch to a combination of the COH bend and an HCH bend, which subsequently couples to high order combination bands involving torsional excitation.
