Raman and surface-enhanced Raman spectroscopy (SERS) studies of bacteria have reported a wide range of
vibrational mode assignments associated with biological material. We present Raman and SER spectra of the amino
acids phenylalanine, tyrosine, tryptophan, glutamine, cysteine, alanine, proline, methionine, asparagine, threonine,
valine, glycine, serine, leucine, isoleucine, aspartic acid and glutamic acid and the nucleic acid bases adenosine,
guanosine, thymidine, and uridine to better characterize biological vibrational mode assignments for bacterial target
identification. We also report spectra of the bacteria Bacillus globigii, Pantoea agglomerans, and Yersinia rhodei
along with band assignments determined from the reference spectra obtained.
