The QUEST project purpose to provide reference excitation energies in order to compare the precision of quantum chemistry methods by statistical calculations. This website is an integral part of this project and makes it possible to dynamically do statistical calculations to determine the best methods for a series of molecules. you can find references for the datasets in the [publication section](publications)
The purpose of the QUEST project is to provide reference (i.e. highly accurate) vertical excitation energies for small- and medium-sized molecules in order to compare the precision of computational quantum chemistry methods thanks to reliable and fair statistical analyses.
One of the key aspect of the QUEST dataset is that it does not rely on any experimental values, avoiding potential biases inherently linked to experiments and facilitating in the process theoretical cross comparisons.
This website is an integral part of this project and makes it possible to dynamically compare the accuracy of a given method with respect to various variables such as the molecule size or its family, the nature of the excited states, the size of the basis set, and many others.
The statistics are showing as data table and as a graph (using the [Plotly JavaScript Open Source Graphing Library](https://plotly.com/javascript))
The corresponding literature references associated with the QUEST dataset can be found in the [publication section](publications)
