FT-Raman of solid rivanol (2-ethoxy-6,9-diaminoacridinium lactate C15H16N3O
-C3H5O3 . H2O) and surface-enhanced Raman scattering (SERS) on silver surfa
ce of rivanol solution at pH 5.5 have been obtained and compared. The assig
nment of vibrational modes has been made for the monocation specie of rivan
ol. SERS spectrum shows a physisorption of rivanol on the silver surface. (
