aFrom experiments where the photolysis of H2O2 was used as the OH source.
bSum of  yields of beta-pinene oxide (1%) and 3-oxonopinone (0.9%). A trace amount of myrtenol was reported but not quantified and is not included in the sum.
cSum of yields of 1-hydroxynopinone (3.1%) and 3-hydroxynopinone (2.2%).
dYield of 3,7-dihydroxynopinone.
eYield of pinonic acid.
