The infrared intensities of the ν2, ν4, and ν9 stretching bands of 1,1-dichloroethylene have been measured in eighteen solvents of different polarity. After correcting for the local field effect, the partial derivatives of the electric dipole moment and electric polarizability with respect to normal coordinates were calculated using the dipole-dipole interaction model. A good or a poor statistical correlation of the calculated and observed intensities then indicates whether this model is adequate or other phenomena are involved in the interaction.
