There are some parameters in the molecular calculationmodel of the pseudo chemical potential (PCP) method that is a new method that thermodynamic formalization is applied in molecular calculation. These parameters were introduced for decreasing errors caused by hypotheses and approximations during theoretical derivation of calculationmodel and up to now the method for obtaining the parameters was not presented. In this paper, we are going to discuss the determining method of parameters introduced to obtain more correct calculation results. The determining method of these parameters have characters of two categories. One of them is determined by calculating on the basis of ionization energy and electron affinity, and the other is estimated by solving normal equation that makes square of difference of calculation values by ab initio method and PCP method into minimum. In this paper, correctness and reliability of the parameters determined was estimated. By investigating the correlation between the PCP and electronegativity, physical meaning of PCP as the scale of mass migration was confirmed and from this result, the reliability of parameter γα was shown. And by inverse calculation of determining equation of interaction parameter kαβ, the correctness of kαβ was confirmed. Like this, it was shown that the parameters determined can be used enough to PCP method for calculating molecular energy and atomic charge.
