Y. Imai et al., OBSERVATION OF SERS OF PICOLINIC-ACID AND NICOTINIC-ACID USING CELLULOSE-ACETATE FILMS DOPED WITH AG FINE PARTICLES, SPECT ACT A, 53(11), 1997, pp. 1697-1700
Surface enhanced Raman (SER) spectra of picolinic acid and nicotinic a
cid were observed using cellulose acetate (CA) films doped with Ag fin
e particles. The spectra obtained match those reported for silver coll
oids though some differences in SER band intensity were observed. The
ease of preparation and handling of the CA film method renders it more
useful than the colloid method for the observation of SER spectra. (C
