Short summary
A great quantity and variety of organic compounds is released to the atmosphere annually. These compounds greatly impact air chemistry, quality and climate. Laser-based experiments were used to study the atmospheric breakdown of three organics: isoprene, alpha-pinene, and delta-3-carene. Results provided important missing information for low-temperature atmospheric conditions, resolved discrepancies from previous work, and allowed estimation of lifetimes of a few hours for each compound.
