Fourier transform surface–enhanced Raman spectra of 1 × 10 −6 M lumiflavin and riboflavin were obtained in silver coloid (pH 7.2) using 1064 nm continuous‐wave laser excitation. These Raman spectra imply that the flavin ring III moiety is coadsorbed on the colloidal silver metal surface through oxygens of C(2)O and C(4)O with the colloid preparation components, the EDTA anion or the NO 3 − ion.
