Abstract
Abstract Infrared and Raman spectra of sodium benzenesulfonate and its fully C-deuterated derivative have been recorded in the solid state and in the aqueous solution. The normal coordinate analysis has been made for C6H5SO3− and C6D5SO3− ions based on the C2V symmetry. A valence force field was assumed and the force constants were refined by the least squares method. It was found that the diagonal force constants for the CH out-of-plane bending vibrations at the ortho and the para positions are greater than the corresponding constant for the meta position. This result reflects well the effect of the electron attractive substituent in monosubstituted benzene derivatives. The force constants obtained were transferred to p-toluenesulfonate ion successfully.
