title: [Are nitrogen bases of DNA hydrated at low humidity?].
abstract: The infrared spectra (1450-1800 cm-1) of DNA films derived at different relative humidity are presented. An analysis of the observed frequency and intensity changes of infrared bonds assigning to the intra- and interring vibrations indicates that the nitrogen bases of DNA become hydrated at low (0-64%) relative humidities.
