Paper reaches 1000 citations

A paper entitled “Characterization of C_H…O hydrogen bonds on the basis of the charge density“, [Koch and Popelier,J.Phys.Chem., 99, 9747 (1995)] just hit the 1000 citation-mark according to the Web of Science.

A paper entitled “Characterization of C_H…O hydrogen bonds on the basis of the charge density“, [Koch and Popelier,J.Phys.Chem., 99, 9747 (1995)] just hit the 1000 citation-mark according to the Web of Science. This article, which was originally rejected by J.Amer.Chem.Soc., started as a bet between the co-author and myself, when we were both postdocs in Cambridge. The work led to a number of criteria to decide on hydrogen bonding. I had no idea that this simple analysis would become so popular, and that it would continue to attract over a hundred citations per annum. This work shows how features intrinsic to (ab initio) charge densities can characterise non-covalent interactions. However, now, a decade and a half later, we start work on a more sophisticated next-generation topological analysis based on atomic energy partitioning, which is expected to yield more robust information.
