    experiment_goals: 'This experiment examined the photoreactivity of isoprene diol with ammonium sulfate aerosol in the absence of an OH precursor.'
    experiment_summary: 'The chamber was humidified to ~75% RH; ammonium sulfate was introduced by atomization, and isoprene diol was introduced in both gas and particle phases via atomization and evaporation. Lights were turned on to initiate photochemistry, and a filter was collected for offline analysis.'
    additional_notes: 'To correct the experimental data, we use the measured particle wall loss rates from the experiment on 11/29/21, measured isoprene diol gas-phase loss rates from the experiment on 11/22/21, and measured product formation rates from the experiment on 12/3/21.'
