Opis

FROM REVIEWS OF THE SERIES

"Reviews in Computational Chemistry remains the most valuable reference to methods and techniques in computational chemistry."
-JOURNAL OF MOLECULAR GRAPHICS AND MODELLING

"One cannot generally do better than to try to find an appropriate article in the highly successful Reviews in Computational Chemistry. The basic philosophy of the editors seems to be to help the authors produce chapters that are complete, accurate, clear, and accessible to experimentalists (in particular) and other nonspecialists (in general)."
-JOURNAL OF THE AMERICAN CHEMICAL SOCIETY
