Summary

THE THEORY OF INDIRECT STATIC INTERACTION BETWEEN DUMBELL IMPURITIES IN ATOMIC MATRICES (SUCH AS NITROGEN IN ARGON) IS CONSTRUCTED. THE PRESENCE OF IMPURITIES AROUND THE CHOSEN ONE ENTAILS RANDOM TETRAGONAL DISTORTIONS WITHIN THE LOCAL VICINITY OF THE CHOSEN IMPURITY AND, AS A CONSEQUENCE, ADDITIONAL SPLITTINGS OF THE DEVONSHIRE SPECTRUM. USING THE KNOWN INTERMOLECULAR POTENTIALS FOR NITROGEN AND CARBON MONOXIDE AS IMPURITIES AND ARGON, KRYPTON AND XENON AS MATRICES, THE AUTHORS EVALUATED THE PHONON-ROTATION COUPLING CONSTANTS AND THE INTENSITIES OF THE RELEVANT INTERACTIONS (IN PARTICULAR, THE PARTIAL COEFFICIENTS THAT DESCRIBE REACTION OF THE ROTOR TO AN ELASTIC-DEFORMATION FIELD AROUND A DILATATION CENTER). FOR THE NITROGEN IN ARGON SYSTEM THE PARAMETERS DETERMINING THE DISTRIBUTION OF THE SPLITTINGS OF THE DEVONSHIRE SPECTRUM ARE EVALUATED AND THE SHAPE OF THERMODYNAMIC TRANSITIONS CONTRIBUTED TO THE LOW-TEMPERATURE HEAT CAPACITY IS CALCULATED.
