Journal of Chemical Theory and Computation is a peer-reviewed scientific journal, established in 2005 by the American Chemical Society. [1] It is indexed in Chemical Abstracts Service (CAS), Scopus, British Library, and Web of Science. The current editor-in-chief is Laura Gagliardi. [2] Currently as of the year 2022, JCTC has 18 volumes. [3]
Much of the JCTC reports on new theories, methods and applications of quantum chemical knowledge, such as electronic structure, molecular mechanics and statistical mechanics. Research of computational applications such as ab initio quantum mechanics, Monte Carlo simulations and solvation model are discussed among others. It is stated that "the Journal favors submissions that include advances in theory or methodology with applications to compelling problems". [4]
The first issue of JCTC was published in 2005 as a bimonthly journal with 133 articles published in the first volume. In 2008, JCTC increased their output to become a monthly publication, producing 12 issues per year. The journal came about when Jorgensen noticed that although theory and computation could be found in many journals, the field did not have a dedicated journal. In year 2008, JCTC took professor Ursula Rothlisberger from the Swiss Federal Institute of Technology as their associate editor. In the year 2009, the editorial team was further expanded with the addition of Professor Gustavo Scuseria from Rice University. [5]
JCTC is ranked number 4 highest in the list of "Physical and Theoretical Chemistry" journals SCImago Journal Rank. JCTC has a weighted rank indicator (SJR) of 2,481 as of the year 2014. To give perspective, the popular multidisciplinary journal Nature (journal) has an SJR factor of 17,313. The journal had an average of 65.73 references per document in 2014. [6] In 2020, the journal had a total of 41,591 citations and an impact factor of 6.006. [4] According to the Journal Citation Reports , the journal has a 2022 impact factor of 5.5. [7]
Computational chemistry is a branch of chemistry that uses computer simulation to assist in solving chemical problems. It uses methods of theoretical chemistry, incorporated into computer programs, to calculate the structures and properties of molecules, groups of molecules, and solids. It is essential because, apart from relatively recent results concerning the hydrogen molecular ion, the quantum many-body problem cannot be solved analytically, much less in closed form. While computational results normally complement the information obtained by chemical experiments, it can in some cases predict hitherto unobserved chemical phenomena. It is widely used in the design of new drugs and materials.
Quantum chemistry, also called molecular quantum mechanics, is a branch of physical chemistry focused on the application of quantum mechanics to chemical systems, particularly towards the quantum-mechanical calculation of electronic contributions to physical and chemical properties of molecules, materials, and solutions at the atomic level. These calculations include systematically applied approximations intended to make calculations computationally feasible while still capturing as much information about important contributions to the computed wave functions as well as to observable properties such as structures, spectra, and thermodynamic properties. Quantum chemistry is also concerned with the computation of quantum effects on molecular dynamics and chemical kinetics.
Theoretical chemistry is the branch of chemistry which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry: for example, the concepts of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular orbitals, orbital interactions, and molecule activation.

Henry Frederick "Fritz" Schaefer III is a computational and theoretical chemist. He is one of the most highly cited chemists in the world, with a Thomson Reuters H-Index of 121 as of 2020. He is the Graham Perdue Professor of Chemistry and Director of the Center for Computational Chemistry at the University of Georgia. Before becoming professor at Georgia he was professor at University of California, Berkeley and in 2004, he became Professor of Chemistry Emeritus, at UC Berkeley
Spartan is a molecular modelling and computational chemistry application from Wavefunction. It contains code for molecular mechanics, semi-empirical methods, ab initio models, density functional models, post-Hartree–Fock models, and thermochemical recipes including G3(MP2) and T1. Quantum chemistry calculations in Spartan are powered by Q-Chem.
Semi-empirical quantum chemistry methods are based on the Hartree–Fock formalism, but make many approximations and obtain some parameters from empirical data. They are very important in computational chemistry for treating large molecules where the full Hartree–Fock method without the approximations is too expensive. The use of empirical parameters appears to allow some inclusion of electron correlation effects into the methods.
Sir David Charles Clary, FRS is a British theoretical chemist. He was president of Magdalen College, Oxford, from 2005 to 2020. He was the first chief scientific adviser to the Foreign and Commonwealth Office from 2009 to 2013. He is a Professor of Chemistry at the University of Oxford.
The Journal of Physics A: Mathematical and Theoretical is a peer-reviewed scientific journal published by IOP Publishing, the publishing branch of the Institute of Physics. It is part of the Journal of Physics series and covers theoretical physics focusing on sophisticated mathematical and computational techniques.
William L. Jorgensen is a Sterling Professor of Chemistry at Yale University. He is considered a pioneer in the field of computational chemistry. Some of his contributions include the TIP3P, TIP4P, and TIP5P water models, the OPLS force field, and his work on free-energy perturbation theory for modeling reactions in solution, protein-ligand binding, and drug design; he has over 400 publications in the field. Jorgensen has been the Editor of the ACS Journal of Chemical Theory and Computation since its founding in 2005.

Paul Anthony Benioff was an American physicist who helped pioneer the field of quantum computing. Benioff was best known for his research in quantum information theory during the 1970s and 80s that demonstrated the theoretical possibility of quantum computers by describing the first quantum mechanical model of a computer. In this work, Benioff showed that a computer could operate under the laws of quantum mechanics by describing a Schrödinger equation description of Turing machines. Benioff's body of work in quantum information theory encompassed quantum computers, quantum robots, and the relationship between foundations in logic, math, and physics.
