Fabrication and Structure of Nucleic Acid Base Thin Films

Abstract
Thin films of nucleic acid bases have been grown on cleaved KBr (100) by evaporation deposition. The structures of the thin films are investigated by infrared spectrometry and X-ray diffraction. The orientation of these molecules on the substrate has also been determined by the measurement of FT-IR (fourier transform infrared reflection) absorbance. It is revealed that adenine and thymine molecules are evaporated on the substrate to form thin films without decomposition.
