Dynamic characteristics of light emission accompanying cryocondensation of nitrous oxide and ethanol
We report new results in the study of cryoradiation accompanying the condensation of some gas. The main objectives of this research are: (i) check a broader range of substances for their ability to cryoradiation; (ii) the study of the nature of radiation and its relaxation characteristics; (iii)...

| description |
We report new results in the study of cryoradiation accompanying the condensation of some gas. The main
objectives of this research are: (i) check a broader range of substances for their ability to cryoradiation; (ii) the
study of the nature of radiation and its relaxation characteristics; (iii) the study of thermally stimulated processes
in condensed samples. Of the compounds tested only nitrous oxide and ethanol exhibited the ability to generate
cryoradiation during condensation from the gas phase. Separate flashes detected by a photomultiplier represent a
superposition of a series of successive relaxation processes of individual regions, somehow related to each other.
It is possible that such areas are crystallites containing a set of molecules of nitrous oxide/ethanol, which are in
metastable states with different activation energies. Radiation by these molecules during the transition into the
ground state induces successive relaxation processes of molecular groups according to their activation energy
distributions. Nonequilibrium radiative states forming in the process of cryocondensation of nitrous oxide and
ethanol may have different nature of the activation energy distribution and this could explain the difference in
the character of the radiation relaxation in these substances.
