IN THE INTRINSIC COORDINATE SYSTEM

The statistics of polymer-chain conformations in the intrinsic 
coordinate system, the directions of whose axes are determined by 
the anisotropy of a polymer coil at certain instantaneous distribution 
of the conformations, is considered. It is shown that even for an 
absolutely flexible polymer chain the shape of the coil in the intrinsic 
coordinate system is anisotropic. Full distribution functions of the 
chain links in space are constructed for both the absolutely flexible 
linear polymer and the linear polymer chain which possesses finite 
flexural rigidity, and degrees of anisotropy of these macromolecules 
are calculated.
