Enhanced Organic Nitrate Formation from Peroxy Radicals in the Condensed Phase.

ABSTRACT: Organic alkoxy (RO) and peroxy (RO₂) radicals are key intermediates in multiphase atmospheric oxidation chemistry, though most of the study of their chemistry has focused on the gas phase. To better understand how radical chemistry may vary across different phases, we examine the chemistry of a model system, the 1-pentoxy radical, in three phases: the aqueous phase, the condensed organic phase, and the gas phase. In each phase, we generate the 1-pentoxy radical from the photolysis of n-pentyl nitrite, run the chemistry under conditions in which RO₂ radicals react with NO, and detect the products in real time using an ammonium chemical ionization mass spectrometer (NH₄ ⁺ CIMS). The condensed-phase chemistry shows an increase in formation of
