Vibrational Study of a Nucleoside Analogue with Antitumoral and Antiviral Activity, 5-Fluoro-2′-deoxyuridine, FdU

Abstract
The advantages of different methods for obtaining a reliable assignment of the vibrational spectra of the antitumoral and antiviral nucleoside analogue, 5-fluoro-2′-deoxyuridine. FdU, are evaluated as a basis for the study of FdU-containing polymers and drug-target interactions. The experimental FT-IR and FT-Raman spectra, are compared with theoretical frequencies obtained by a classical mechanics method and a semiempirical molecular orbital (MO) method, PM3.
