This book begins by providing a simplified version of the computational quantum chemistry sufficient to calculate the wavefunctions that are the basic input of NG-QTAIM. Enough basic (scalar) QTAIM theory is provided to understand the later chapters. In addition, our developments of scalar QTAIM are presented and activities at various levels of difficulty are provided for the readership to facilitate understanding.  The topological origins of Quantum Theory of Atoms in Molecules (QTAIM) before explaining the highlights and consequences of the developments of Next-Generation QTAIM (NG-QTAIM) that is a 3-D vector-based realization of QTAIM. The book compiles all developments and extensions of Next-Generation QTAIM in one place for easy reference for those engaged in theoretical/computational chemistry. Essential insights into molecular switch functioning not available from the energy barrier or any scalar measures are presented along with a new measure toassess the efficiency of rotary molecular motors. The book also discusses how the treatment of external forces such as electric fields and laser irradiation is included in NG-QTAIM. This book benefits theoretical/computational chemists/physics/engineers, students (graduate and undergraduate) and chemical/pharmaceutical industry researchers who carry out chemical computations in universities and industries.Where appropriate, Target Learning Outcomes and Further Reading are provided along with a list of the scientific goals to be addressed in addition to a glossary table in the summary sections. Where applicable each chapter concludes by outlining benefits, limitations and suggestions for further investigations.All our NG-QTAIM publications are available as pre-prints in the form of .pdf files along with the corresponding supplementary materials at our BEACON website www.beaconresearch.org.

Über Autor(innen)

Samantha Jenkins obtained her doctorate from Salford University in 2000. Then, she was a postdoctoral fellow at Sussex University, UK, and then McMaster University, Canada, before spending eight years in Sweden obtaining a track record of Industrial-based funding (KK Stiftelsen) and a docent in 2006 (associate professor level) before moving to Hunan Normal University in 2010 to become a professor and has won several National Natural Science Foundation of China (NSFC) grants. Her long-standing interest has been the development of the Quantum Theory of Atoms (QTAIM), in particular developing Next-Generation QTAIM that is the only chemical theory that can provide meaningful interpretations of isoenergetic situations.Steven Robert Kirk obtained his doctorate from Salford University in 2001 followed by a postdoctoral position in McMaster University, Canada. He was a senior project researcher in Sweden before moving to Hunan Normal University in 2010 to become an associate professor in 2010 and a full professor in 2011. He is the project manager for the open-source development-site QuantVec (renamed from AIMPAC2) approved by R.F.W. Bader, the founder of the theory of atoms in molecules (QTAIM). The following open-source and commercial software that includes but not limited to: Integrity, AIMALL, Abinit, Yambo, Gaussian09B, Quantum-Espresso, NWChem, SHARC-MD, OpenMOLCAS, Heidelberg MCTDH, QUANTICS and ORCA codes as well as our QuantVec package.
