Vibrational spectra of phenylfluorone and their interpretation

Fourier-transform IR absorption, Raman, and surface-enhanced Raman scattering spectra are presented for phenylfluorone, which is widely used as an analytical reagent in the photometric determination of high-valent metals from Groups III–VI of the Periodic Table. A geometric structure and vibrational...

Summary:Fourier-transform IR absorption, Raman, and surface-enhanced Raman scattering spectra are presented for phenylfluorone, which is widely used as an analytical reagent in the photometric determination of high-valent metals from Groups III–VI of the Periodic Table. A geometric structure and vibrational frequencies for the phenylfluorone molecule were calculated using a quantum-mechanical density-functional method. An interpretation of its vibrational spectra was proposed for the first time. Spectral effects of phenylfluorone protonation have been studied. The geometry of phenylfluorone adsorbed on the surface of nanostructured silver films was examined.
