Line broadening of carbon oxide in the volume of aerogel nanopores
- 22 Downloads
Calculations of line broadening and shift of carbon monoxide (CO) molecules confined in nanoporous media are presented. A model is considered in which the line broadenings and shifts are caused by collisions of free CO molecules with walls and adsorbed CO molecules with and without rotational degrees of freedom.
