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.
