CRYOCRYSTALS CO2 AND N-2 - GROWTH-RATE, R EFRACTIVITY AND IR REFLECTION SPECTRA

The results are discussed of an experimental investigation into the gr owth rate, refractivity and IR reflection spectra of the real nitrogen and carbon dioxide cryocrystals as a function of the conditions of th eir formation, i.e. the temperature of the condensation surface and th e pressure of the gaseous phase. it is found that the growth rates and refractivity of CO2 vary nonlinearly with the temperature that may be explained by a gradual increase in the amount of defects in the cryst al with decreasing condensation temperature. This conclusion is indire ctly supported by the results of investigation of the temperature depe ndence of the IR reflection spectra of CO2 cryocrystals. It ts suppose d that the structural-morphological characteristics of real cryocrysta ls are independent on the temperature of their formation. The temperat ure variations of the layers of CO2 cryocrystals formed at different t emperatures do not cause substantial changes of the layers.
