On the Shape of the Boundary of Adsorption Lines of Molecules under the Limited Volume

The authors complete calculations of the boundary of adsorption lines of CO and CO2 molecules under the limited volume. The cells with the transverse size from 10 to 200 nm are considered. The inaccuracy of the half-breadth of the lines appearing when the cylindrical and spherical cells are modeled with rectangular cells was estimated. When calculating the shifts and the half-breadth of the lines of CO and CO2 molecules the authors consider the model in which CO and CO2 molecules adsorbed on the walls of the pore may cease their rotational motion.
