✦ Synopsis

The opt/ca/constants of CO 2 cryodeposit were measured in the wavelength range from 2. 5 iJrn to 21.4 IJ[n below 90 K. The peak assigned to the Q branch of v 3 which grew largely at lower temperatures was found and was considered to show that the linearity of the molecule was broken due to the increase in lattice imperfections The data of the real part of the complex refractive index at 4000 crn -1 were applied to obtain the density of CO 2 cryodeposit as a function of temperature. The result showed that the number of void and lattice imperfections increased at lower deposition temperatures. The measured optical constants were analysed by dispersion equations to be used for the calculation of the optical properties and thermal radiative properties of surfaces with CO 2 cryodeposit.
