Bk. Novosadov et Oy. Nikitin, FRAGMENT-WISE ELECTRONIC-STATE CALCULATION FOR LARGE MOLECULAR-SYSTEMS, Journal of structural chemistry, 34(1), 1993, pp. 27-32
A fragmentwise calculation method is presented for the electronic stat
es of molecular systems containing 100-1000 or more atoms. Simple rule
s are formulated for splitting up a polyatomic molecule into fragments
. The performance is demonstrated on the characteristics of substitute
d phenyls.
