This paper includes the first major assessment of the CAM-B3LYP exchange–correlation functional proposed by Yanai, Tew and Handy in 2004. The huge success of this functional (it has now received nearly 1000 citations) is in part due to the results of this work, which showed that CAM-B3LYP was on average either as accurate as, or more accurate than, the prolific B3LYP functional of Becke, Lee, Yang and Parr. The research included in this paper was actually undertaken during the final year of my Masters, during the 4th year project. It has become a standard reference for discussing the accuracy of CAM-B3LYP, as it presents an assessment against a much wider set of data than the original Yanai paper.
