2.4 ACGC method
The ACGC model is combined of group contributions and
position factors contributions.
Formula (4) is used for T c,V c. Formula (5) is used forP c.
αi is the
contribution coefficient of group; βk is the
contribution coefficient of the atomic connectivity factor.αi and βk are shown in
Table S2~S4 of Supporting Information
(contribution-coefficient.docx). Gi is
Gf or Gg .
Gg is the group number and
Gf is the group number divided by SF. The value
of the localization factor (φk ) for each group is
expressed by the calculated value of one of the formulas for the eight
atomic connectivity factors.
