GMTKN55, a database for general-main group thermochemistry, kinetics and noncovalent interactions for the assessment of electronic-structure methods. Our three papers combined constitute one of the most comprehensive and largest DFT benchmark study.

The database itself can be accessed throug this external link.

The GMTKN55 paper, incl. the large DFT benchmark study, can be found here free of charge.

Our first update analysing double-hybrid DFT can be found here.

Our current recommendations based on the analysis of 325 dispersion-corrected and -uncorrected density functional approximations can be found here.

Our account for non-experts and students new to the field can be found here.
