Welcome

The Goerigk group in October 2017

Welcome to the Goerigk Research Group website. Our research at the School of Chemistry at The University of Melbourne, Australia, revolves around the exciting field of Quantum Chemistry, which is the description of electrons in chemical systems by evoking the laws of Quantum Mechanics. Our interests comprise both the development of new quantum-chemical methods, as well as applications to Organic-, Inorganic-, Physico- or Biochemical problems. We have established a range of national and international collaborations with experimental and other theoretical groups, and our research is supported by various local, national and international funding schemes. Please feel free to explore our website through the links provided in the right-hand sidebar (or at the bottom of the page, depending on your device).

8 November 2017:

We are proud to announce publication of our new GMTKN55 database for general main-group thermochemistry, kinetics and non-covalent interations, which we used to assess nearly 220 dispersion-corrected and -uncorrected Density Functional Theory (DFT) approximations.

DFT ­— a methodology that has been acknowledged with the Nobel Prize in Chemistry in 1998 — has become the most important tool for chemists to study chemical systems computationally. While being used by thousands worldwide on an every-day basis, it also has its disadvantages, for instance, hundreds of variations of DFT exist that all differ in reliability, which therefore leads to confusion within the user community.

 

A recent study by us — in collaboration with the Grimme group in Germany — provides guidelines to navigate through this plethora of methods. We present a large database to assess a method’s accuracy, which we used in one the largest DFT assessment studies to provide clear guidelines to the method user and to eliminate popular misconceptions in this area. Our recommendations are the result of a project that lasted nearly three years and required about 2 million CPU hours on high-performance computing clusters.

 

We hope that the reported findings will influence the way chemists carry out computational DFT studies in the future and that GMTKN55 will be adopted as a new standard for the assessment and development of electronic-structure methods.

Our article was published in Physical Chemistry Chemical Physics, and can be found here.
