Thanks to what has been achieved by Fourier transformation, infrared analysis can now become a state-of-the-art device in quality control laboratories if we consider its precision and the gain in time it ensures. Moreover, an increasing number of new

A preliminary investigation of the vibrational properties of anthocyanidins, the most important group of plant pigments, is presented. The results indicate that the visible chromophore is mainly located on the benzopyrylium moiety and emphasize the c
