are required to obtain a faithful estimation of these distributions from a set of measured isotherms. Once the correct energy distribution(ED) is known, the pore size distribution can be computed (or vice versa) with high accuracy using reliable analytical...

. All fundamental vibrational bands were assigned to the normal modes with the aid of the potential energy distribution (PED) values obtained from normal coordinate calculations. To study the internal rotation of CH3 groups, single CH3 rotation...
