Comment on 'Density functional theory study of 1,2-dioxetanone decomposition in condensed phase'.

In the preceding paper results are presented, which are in serious conflict with state-of-the-art ab initio method. Based on these new results the authors propose a new explanation of the reason for the preferential production of a phosphorescent state. Here we show that these controversial results are flawed, since the model use exclude biradical electron structures. © 2012 Wiley Periodicals, Inc. [ABSTRACT FROM AUTHOR]
