How to cite TCA articles

As of January 2012, each article published in TCA is assigned a unique number, e. g. 1071 in the case of “Electronic structure theory: present and future challenges” by So Hirata published in Vol. 131. This number is to be included in the citation alongside the volume number, e. g. Theor Chem Acc (2012) 131:1071. The number also shows up in the Digital Object Identifier (DOI), e. g. DOI 10.1007/s00214-011-1071-0.
