Abstract
The detail mode characters of the C-H bends with Darling-Dennison coupling in the bath of the stretches of acetylene are analyzed in the coset represe ntative space SU(2)/U(1). Besides the local and normal modes, the precessio nal mode [Mol. Phys. 53 (1984) 961; J. Chem. Phys. 105(1996) 10743] is also reproduced. The analysis shows that the excitation of the C-C stretch will lead to more trans local modes for high excitation of the bend. This is pr one to the isomerization of acetylene to vinylidene.
