Profile of orientation

The obvious thing would be to regard the density profile as product of the so-called particle density profile nM z) and the so-called profile of orientation distribution 0(2, w). The particle density profile can be accessed integrating the density profile along the molecular orientations,... 

The particle density profile describes the mean density of molecules at the distance 2 to the pore wall. The profile of orientation distribution describes the distribution of molecular orientations u> = 0,4> at each 2. Any orientation distribution normalizes by / du> o(z,u ) = 1. If the orientations of axially symmetric molecules are isotropic distributed, then it follows from 0(2,w) = const the isotropic profile 0(2,u>) = (4a ). In this case all reachable orientations appear with the same probability.
