The editors of this volume have compiled an important book that is a useful vehicle for important computational research - in the development of theoretical methodologies and their practical applications. Themes include new methodologies, state-of-the-art computational algorithms and hardware as well as new applications. This volume, Practical Aspects of Computational Chemistry IV, is part of a continuous effort by the editors to document recent progress made by eminent researchers. Most of these chapters have been collected from invited speakers from the annual international meeting: “Current Trends in Computational Chemistry” organized by Jerzy Leszczynski, one of the editors of the current volume. This conference series has become an exciting platform for eminent Theoretical/Computational Chemists to discuss their recent findings and is regularly honored by the presence of Nobel laureates. Certainly, it is not possible to cover all topics related to the Computational Chemistry in a single volume but we hope that the recent contributions in the latest volume of this collection adequately highlight this important scientific area.

Practical Aspects of Computational Chemistry I: An Overview of the Last Two Decades and Current Trends gathers the advances made within the last 20 years by well-known experts in the area of theoretical and computational chemistry and physics. The title itself reflects the celebration of the twentieth anniversary of the “Conference on Current Trends in Computational Chemistry (CCTCC)” to which all authors have participated and contributed to its success. This volume poses (and answers) important questions of interest to the computational chemistry community and beyond. What is the historical background of the “Structural Chemistry”? Is there any way to avoid the problem of intruder state in the multi-reference formulation? What is the recent progress on multi-reference coupled cluster theory? Starting with a historical account of structural chemistry, the book focuses on the recent advances made in promising theories such as many body Brillouin-Wigner theory, multireference state-specific coupled cluster theory, relativistic effect in chemistry, linear and nonlinear optical properties of molecules, solution to Kohn-Sham problem, electronic structure of solid state materials, development of model core potential, quantum Monte Carlo method, nano and molecular electronics, dynamics of photodimerization and excited states, intermolecular interactions, hydrogen bonding and non-hydrogen bonding interactions, conformational flexibility, metal cations in zeolite catalyst and interaction of nucleic acid bases with minerals.
