The infrared spectra of gas-phase uracil, thymine, and adenine have been recorded from 100 to 3700 cm(-1) at a resolution of 1 cm(-1). The vibrational band positions and qualitative band intensities are reported and compared to published matrix data as well as to theoretical calculations. Our work suggests that gas-phase emission spectroscopy is a sensitive technique for recording spectra of organic and biological molecules. (C) 1997 Elsevier Science B.V.
