Vibrational spectra of benzylidene aniline, o-hydroxybenzylidene o-hydroxyaniline and its complexes with Cu(II) and Ni(II) metal ions

摘要

The FTIR and FT Raman spectra of benzylidene aniline, and o-hydroxybenzylidene o-hydroxyaniline compounds in the solid state in the wavenumber (1800-200 cm(-1)) are recorded. An assignment for nearly all fundamentals are proposed. Comparison of the spectra of trans stilbene and benzylidene aniline reveals that nu N-Ph stretch for the latter compound is situated at 1368 cm(-1) in the IR spectra with medium intensity. For o-hydroxybenzylidene o-hydroxyaniline, the stretching modes nu N-Ph, and nu C-Ph are observed at 1356 and 1226 cm(-1) respectively. The two nu O-Ph are observed as intense bands in the IR spectra at 1245 and 1278 cm(-1), respectively. The FTIR spectra of the o-hydroxybenzylidene o-hydroxyaniline complexes with Cu(II) and Ni(II) metal ions are also recorded and assigned. [References: 11]
