Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain. ACS cannot be held responsible for errors or consequences arising from the use of information contained in these “Just Accepted” manuscripts.

Box 513, 5600 MB Eindhoven, The Netherlands KEYWORDS. Reaction mechanisms; systems catalysis; computational chemistry; density functional theory; molecular modeling; heterogeneous catalysis; homogeneous catalysis. Over the last decade, computational chemistry has become one of the key components of catalysis research and has deserved a place in the catalysis toolbox next to such common laboratory techniques as infrared spectroscopy (IR), nuclear magnetic resonance (NMR) and X-ray diffraction (XRD). It would not be an exaggeration to state that the progress in fundamental understanding of catalytic phenomena currently relies largely on computations.1 Computations have become indispensable in providing an atomistic framework for the interpretation of spectroscopic data and elucidation of catalytic mechanisms. State-of-the-art quantum chemical methodologies and, particularly, the density functional theory (DFT) methods are well-suited for studying chemical reactivity,1 analyzing complex reaction paths,2 and modeling kinetics of catalytic reactions.3 Theoretical studies provide important guidelines for the development of new and improved catalyst systems ranging from heterogeneous transition metal4 and zeolite5 catalysts to enantioselective organocatalysts.6 Accuracy is the corner stone of computational chemistry and it remains an important research topic of the theoretical community.7 Modern quantum chemistry provides the computational tools suitable for resolving chemical phenomena with
