Abstract
It is assumed that orientation fluctuations for molecules in a liquid form an uncorrelated Markov process, and an expression is derived in quadratures for the initial chemical polarization of the electrons formed by the triplet mechanism. The expression applies for any magnetic field strength and solvent viscosity. If the molecular rotations are slow and the magnetic field is weak, one can perform numerical calculations on the electron chemical polarization.
