Analytical formula for correction factor in the expression for nucleation rate taking account of the contribution from translational and rotational degrees of freedom to critical nucleation center free energy is proposed. This formula may be applied to a wide variety of systems. It has been derived on the basis of Reiss correction formula (1998) (with allowance for translational degrees of freedom only) with the contribution from rotational degrees of freedom to the critical nucleation center free energy taken into consideration.
