“…These bands exhibit relevant frequency shifts, broadening and/or changes in shape passing from physical mixtures to inclusion complexes, indicating alterations in the microenvironment of the drugs as a consequence of the formation of hydrogen bonding and the presence of van der Waals forces during their interaction to form the inclusion complex [33,35,47,48]. For quantitatively accounting the changes in the hydrogen bond network as a consequence of complexation, the O-H stretching vibration has been deeply analysed by using curve-fitting technique in order to separate the contribution of the individual vibrations to the experimental profile.…”

“…The investigation of the interactions, at molecular level, of isoflavones and CyD derivatives by UV, circular dichroism and FTIR spectroscopic methods has been already performed [33][34][35][36][37][38]. These studies were focused on the molecular inclusion between isoflavones and highly soluble, non-aggregating, chemically modified b-CyDs.…”

“…In the most important spectral region, between 1700 and 1550 cm À1 , multiple band overlapping occurs. The application of deconvolution to spectra has removed the multiple band overlapping limitations (Pappas et al, 2004;Cannavà et al, 2008;Carbonaro and Nucara, 2010). This development has been facilitated by the application of secondderivative spectroscopy.…”
