In this study, the comprehensive theoretical and experimental investigations of Raman (RS) and infrared absorption (IR) spectra of bradykinin (BK) are presented. The ab initio Born-Oppenheimer molecular dynamics (BOMD) calculations, in the presence of water molecules that form the first coordination sphere, were used for conformational analysis of the BK structure. Based on the Density Functional Theory (DFT) calculations at the B3LYP/6-311G(d) level the vibrational spectra were interpreted. The calculated frequencies were scaled by means of the effective scaling frequency factor (ESFF) method. The theoretical data, which confirm the compact structure of BK in the presence of the water molecules revealed the remarkable effect of the intermolecular hydrogen bonding on the BK structural properties.
