A comparative Raman and FTIR study of carnosine, a dipeptide present in several mammalian tissues, and its complexes with copper(II) at different pH values was carried out. The neutral imidazole ring gives rise to some bands that appear at different wavenumbers, depending on whether the imidazole ri

## Abstract We have shown previously that the Nβmethylpridyl group vibrations of waterβsoluble porphyrins, M(TMpyβP4), are shifted to lower frequencies (0.5β2.6 cm^β1^) as a result of coulombic interaction between the N^+^βCH~3~ group of M(TMpyβP4) and the PO~2~ group of a nucleic acid. We have now
Raman di β erence spectroscopy (RDS) can be employed successfully and generally to overcome the problem of spectral crowding in Raman measurements of large macromolecules, such as proteins. In such an experiment, a protein is "taggedΓ in some way and the di β erence spectrum between the protein and it
