title: [Anomalies in the dielectric properties of cytosine monohydrate monocrystals and textured anhydrous cytosine polycrystals].
abstract: Measurements were taken of dielectric constants of cytozin-monohydrate monocrystals and nonaqueous cytozin polycrystals within a wide temperature range (77-410 K) and along different crystallographic directions. A number of anomalies were found in dielectric constant of these compounds, as well as phase transition of cytozin-monohydrate into nonaqueous modification. Energies of hydrogen bonds OHN and OHO in monocrystals of cytozin-monohydrate and approximate relaxation time were estimated.
