An exciting development in the plasmonic nanomaterials field is the discovery of their ability to mediate a broad variety of chemical reactions. To achieve the full potential of these materials as solar-driven photocatalysts, a mechanistic understanding of plasmon-driven chemistry is required for further optimization. Here we describe our use of ultrafast surface-enhanced Raman spectroscopy (SERS) to probe molecule-plasmon dynamics on the ultrafast timescale of nuclear motion and chemical reactivity.  We examine contributions of plasmon-derived hot carriers, localized heating, and energy transfer to molecular photochemistry on the ultrafast timescale, and discuss implications of these processes for the plasmonic photocatalysis field.<br/><br/>
