IR study of the dimerization and the proton acceptor ability of N - tertio -butoxycarbonyl- l -phenylalanine

FTIR studies of tyrosine oxidation at polycrystalline Pt and Pt(111) electrodes

“…Either if there was a random orientation of the molecule at the surface or a defined adsorption (aromatic ring parallel or perpendicular orientation), the phenol or hydroquinone molecule produces quinone derivates in acid solution at a smooth or a rough platinum surface [46][47][48]. Moreover, different authors have conducted FTIR spectral measurements on phenol complexes with amino acids [49] and betaines [50] to prove the formation of dimers through the characteristic bands of the phenolic group. We have check for these signals conducting in situ FTIR spectra of hydroquinone ( Fig.…”
