Surface-enhanced hyper-Raman scattering (SEHRS) and surface-enhanced Raman scattering (SERS) using mode-locked Ti: sapphire laser excitation is reported. SEHRS and SERS from crystal violet molecules on colloidal silver were measured using 1 ps laser pulses (82 MHz repetition rate, I .2 W average pow
Experimental evidence is given for surface complexes consisting of metal-adatom, pyndme and halide ions with which the surface enhanced Raman process can occur. A large part of the enhanced continuum turns out to result from a superposition of numerous extremely weak SER hnes attributed to these com
