Goals:
This experiment was done to react Isobutyraldehyde with OH in the high NO2 condition to compare to MACR's oxidation mechanism. Isobutyraldehyde is analogous to MACR except instead of the double bond it has a single bond, so OH addition doesn't take place. Temperature is 25-26 degC.

Summary:
The reaction did not produce any significant amounts of SOA.
