✦ Synopsis

A physrcal model IS presented for the orrgm of very low frequency hbralronal modes seen m the enhanced Raman spectrum of pyrrdme and CN-on an electrochemrully prepared silver surface The Image dipole of the molecule provides a anharmomc restorm_e torque for molecules adsorbed 111th theu dipole moment perpendrcular to the surface. The calculated hbratronal modes are in reasonable agreement wrth elperrment
