Abstract
Usually the conventional theories consider
the lo\~ temperature plasma as a system containing mobile
charged particles and neutral atoms or molecules. In
this thesis the theory of some collective properties of
"dipole plasma" that consists of charged particles and
polar molecules with constant dipole moment as the neutral
component is developed.
In such a plasma the dipoles interact "'ith the
charged particles and the self-consistent fields that arise
in the non-equilibrium state of the plasma. '1'he interactions
",ith the electrons and positive ions result in some
correction terms in the thermodynamic functions of plasma;
",hereas, the dipole interactions with the self-consistent
flelds lead to some new physical effects such as the
shifting of plasma frequencies, and appearance' of additional
damping plasma waves and a new branch of eigen-vibration
which we call the "dipole-acoustic "lave".
'rhese phenomena in dipole plasma are investigated with the
help of a collisionless kinetic equation derived for the
rotational degrees of freedom of the dipoles.
The dielectric t.ensor is calculated from a perturbation
analysis on the distribution function of the dipole plasma
