Abstract: Polarized atmospheric molecules always tend to move where the electric field intensity is high. On the other hand, their random movements oppose this tendency. As a result, the stronger is the field, the thicker is the molecular concentration. Is it thicker, the atmospheric molecular distribution near a high voltage transmission line than somewhere else？ An equation of atmospheric molecular concentration in electric field is deduced from Boltzmann distribution. It is found out that the influence of electric field on atmospheric molecular concentration is very little.

Key words: polarization, dipole moment, Boltzmann distribution, molecular concentration
