The multiplets arising from the resonance coupling in the $\alpha$- and $\beta$-crystal at $-165^{\circ} C$ have been characterized for three of the fundamental vibrations of the molecule: $\nu_{3}(A_{1})$, the symmetric methyl deformation mode; $\nu_{6}(E)$, the asymmetric methyl deformation mode; and $\nu_{7}(E)$, the asymmetric methyl wagging mode. Finally, the multiplets have been observed for the first time for the $\alpha$-crystal, the phase which is the thermodynamically stable at a low temperature. en_US dc.format.extent 96204 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title AN INFRARED INVESTIGATION OF THE $\alpha$ TO $\beta$ CRYSTAL TRANSITION IN ACETONITRILE en_US dc.type article en_US
