In this section, learn about the chemistry of terpenes and essential oils, key components of fragrances.. a) Essential oils. Learning intention. Learn about the constitution, properties and uses of essential oils.. Approach. Derive new empirical parameters to represent (1) the dynamic evolution of SOAs in smog chambers as a function of NO. x. -dependent multigenerational chemistry and (2) losses of gases and particles to walls.
