A fundamental molecular level understanding of atmospheric processes is central to the development of accurate predictive models that can optimize paths forward for a sustainable future. The complexity of chemical mixtures, the large number of different species found in the environment and the widely varying conditions and media in which they are found presents a significant challenge that requires a variety of approaches. It has become particularly clear that a combination of experiments and theory are required to provide the molecular insight that is the foundation for parameterization of such processes in models. Several recent examples from this lab illustrating the power of the combination of experiments and computation will be presented. These include processes relevant to new particle formation and growth in the atmosphere, and the environmental fates of some neonicotinoid pesticides that absorb in the actinic region.
