TLDR
In this paper, the carbonyl products of isoprene, methacrolein (MTA), methyl vinyl ketone (MVK), hydroxyacetaldehyde, and Hydroxyacetone have been identified and their concentrations measured in experiments involving sunlight irradiations of 1 ppm organic and 200 ppb NO in purified air.Abstract:
The carbonyl products of isoprene, methacrolein (MTA), methyl vinyl ketone (MVK), hydroxyacetaldehyde, and hydroxyacetone have been identified and their concentrations measured in experiments involving sunlight irradiations of 1 ppm organic and 200 ppb NO in purified air. The MTA/MVK yield ratio was 1.4 for isoprene. The hydroxycarbonyljmethylglyoxal yield ratio was 4.3 for MTA and was 1.9 for MVK. The peroxyacyl nitrates PAN [RC(O)OONO 2 , R=CH 3 - ] and MPAN [R=CH 2 C-(CH 3 )-] have been measured. MPAN/PAN concentration ratios were 0.65±0.04 for isoprene and 2.3±0.1 for MTAread more

Biogenic Volatile Organic Compounds (VOC): An Overview on Emission, Physiology and Ecology
TL;DR: In this article, an overview of the actual knowledge of the biogenic emissions of some volatile organic compounds (VOCs), i.e., isoprene, terpenes, alkanes, alkenes, carbonyls, alcohols, esters, and acids, is presented.

Protocol for the development of the Master Chemical Mechanism, MCM v3 (Part A): tropospheric degradation of non-aromatic volatile organic compounds
TL;DR: In this paper, an update to the previous protocol is presented, which has been used to define degradation schemes for 107 non-aromatic VOC as part of version 3 of the Master Chemical Mechanism (MCM v3).

The tropospheric degradation of volatile organic compounds: a protocol for mechanism development
TL;DR: In this paper, a series of rules for the construction of detailed degradation schemes for use in numerical models of the boundary layer over Europe is presented. But, as a major disadvantage of explicit chemical mechanisms is the very large number of reactions potentially generated, if the rules are rigorously applied.

Isoprene forms secondary organic aerosol through cloud processing: model simulations.
TL;DR: It is concluded that cloud processing of isoprene is an important contributor to SOA production, altering the global distribution of hygroscopic organic aerosol and cloud condensation nuclei.
