【Abstract】 The assignment of the fundamental frequencies of C4H2 given by Timm and Mecke is discussed and a new assignment in accord with the selection rules is suggested. Nine force constants for the molecule are calculated according to Timm and Mecke’s assignment, while the new assignment gives no reasonable constants for the deformation vibrations. Further study of the Raman spectrum and the infrared absorption is necessary for a final classification of the deformation frequencies.更多还原
