WebSep 16, 2024 · Abstract. A new instrument for the measurement of atmospheric nitrous acid (HONO) and hydroxyl radicals (OH) has been developed using laser photofragmentation (LP) of HONO at 355 nm after expansion into a low-pressure cell, followed by resonant laser-induced fluorescence (LIF) of the resulting OH radical fragment at 308 nm similar to the … WebLa photo-oxydation, généralement appelée photofragmentation de type II de Norrish, est particulièrement adaptée pour la libération contrôlée de composés carbonylés volatiles, mais nécessite que le précurseur soit sensible à la lumière en plus d’être sensible à l’oxygène, et que le solvant soit polaire [14].
