Molecular surrounding media as an important factor can effect on the operation of wide variety of drugs. For
more study in this paper, spectral properties of Methotrexate and Folinic acid have been studied in various solvents.
Our results show that the photo-physical of solute molecules depend strongly on solute-solvent interactions
and active groups in their chemical structures. In order to investigate the contribution of specific and
nonspecific interactions on the various properties of drug molecules, the linear solvation energy relationships
concept is used.Moreover, charge distribution characteristics of used sampleswith various resonance structures
in solvent environmentswere calculated bymeans of solvatochromic method. The high value of dipolemoments
in excited state show that local intramolecular charge transfer can occur by excitation. These results about molecular
interactions can be extended to biological systems and can indicate completely the behaviors of Methotrexate
and Folinic acid in polar solvents such as water in body system.
