✦ Synopsis

A zero-order normal coordinate analysis was made for o-, m-and p-dimethoxybenzenes and 1,2,3-, 1,2,4-and 1,3,5-trimethoxybenzenes by transferring the force constants from our earlier work. The observed and calculated frequencies agree with an average error of 14.7 cm-'. Unambiguous vibrational assignments of in-plane fundamentals of the six molecules have been made, and several assignments suggested by earlier workers have been revised.
