  1. Huff Hartz Research Group • What are aerosol yields from a precursor mixture that reflects the complexity of atmospheric emissions? • Do the aerosol yields in smog chamber experiments mimic those found in the atmosphere? • What are the oxidation products of biogenic precursor mixtures? • Our approach: essential oils
