In this work, the spectroscopy of epigallocatechin-3-gallate (EGCG) and EGCG bonded to 1,2-dipalmitoyl-sn-glycero-3-phospho-(1′-rac-glycerol) (sodium salt) (DPPG) lipid is studied both experimentally by combining high-resolution vacuum ultraviolet (VUV) photo-absorption measurements in 4.0–9.0 eV energy range theoretical calculations using density functional theory (DFT) methodology. There a good agreement between experimental data, inclusion solvent implicitly explicitly further improves agreement. For all measured absorption bands observed VUV spectra water, assignments calculated electronic transitions are provided. The reveal that spectrum DPPG-EGCG has an intense peak around 150 nm, which accordance with it assigned electron transfer transition from resorcinol–pyrogallol groups different smaller molecule. Finally, increase absorbance can be associated interaction molecules.
