abstract = {The development of (semi-)explicit chemical kinetic models
for atmospheric chemistry relies on an accurate assessment
of the reaction rates and product yields for the elementary
reactions in the model. For a large fraction of the
reactions in an extensive oxidation mechanism, no direct
experimental or theoretical data exists, or the information
available does not span the required range of reaction
conditions. Structure-activity relationships (SARs) are then
used to predict the required data, where each SAR captures
the known reactivity trends for a given reaction class.
Preferably, the SAR links the molecular structure directly
to the reactivity, without the need of additional input data
beyond the molecular graph.Experimental and theoretical
studies are highly complementary to derive SARs. In recent
years, the improved predictive capabilities of theoretical
methods, and the ability to affordably examine systematic
series of reactions in a given class theoretically, have
allowed theory-based data to become an important source of
information in the development of SARs. A number of recent
SARs will be discussed, in which theory-based methods have
played an important role in their formulation. This includes
recent SARs on the H-migration in alkylperoxy radicals, as
well as systematic data on alkoxy radical decomposition, and
the reactions of oxygenated Criegee intermediates. Where
possible, the performance of these SARs will be compared to
experimental data.},
