MNDO study of refrative index and dispersion of P2O5 glass
Autor: M. V. Artamonova, S. G. Kozhevatkin, V. I. Molev
Publikováno v: Journal of Non-Crystalline Solids. 152:270-272
The geometry, refractive indices and dispersion of the H 4 P 2 O 7 structural unit were calculated by the MNDO CI (configurational interactions) semi-empirical molecular orbital method. The optimized geometry and calculated properties showed a good a
