After the second edition introduced first density functional theory aspects, this third edition expands on this topic and offers unique practice in molecular mechanics calculations and DFT. In addition, the tutorial with its interactive exercises has been completely revised and uses the very latest software, a full version of which is enclosed on CD, allowing readers to carry out their own initial experiments with forcefield calculations in organometal and complex chemistry.

Peter Comba is Professor of Inorganic Chemistry at the University of Heidelberg, Germany. He obtained his Ph.D. in 1981 from the University of Neuchatel, Switzerland. After postdoctoral positions at the Australian National University and the University of Lausanne and the habilitation at the University of Basel, he moved in 1992 to Heidelberg. He received the Humboldt South Africa Research Award in 2000 and had visiting professorships at the Universities of Leiden, ANU, Pretoria, Brisbane and Osaka. His research includes theory and experiments in transition metal coordination and bioinorganic chemistry – molecular modeling, spectroscopy, magnetochemistry, thermodynamics, kinetics and mechanisms, synthesis and catalysis.
Trevor Hambley is Full Professor at The University of Sydney, Australia. He received his Ph.D. in 1982 from the University of Adelaide, followed by a postdoctoral stay the Australian National University. He received the Edgeworth David Medal in 1989 and awards for Research Supervision and Teaching in 1997, 1998, and 2008. His research interests are focused on hypoxia and tumour selective agents, Pt anti-cancer drugs, matrix metalloproteinase targeting agents, and drug design and development.
