Description
The UV photochemistry of cis-Pinonic Acid has been studied in cryogenic matrices, as well as that of these complexes with water and oxygen.This molecule, which is of interest in the atmosphere, is one of the products of the decomposition chain of alpha- and beta-pinenes into a tri-acid: MBTCA. This decomposition occurs through the successive or simultaneous action of hydration, ozonolysis, and solar irradiation. Understanding the role of water (and oxygene) coupled with solar irradiation during this aging process is particularly important to address isomerization or fragmentation processes. I will present the latest results obtained on this system, for which not even the infrared (IR) spectrum has been published.
