Goals:
This experiment was performed to study product formation from stabilized Criegee intermediates (SCI) in the Isoprene + ozone under various relative humidity (RH) conditions with cyclohexane as an OH scavenger. This investigates the reaction of the simplest SCI (CH2OO) with water and water dimer

Summary:
Significant amounts of CH2OO + H2O products (HMHP, formic acid, and H2O2) were observed
