Qualidade:
the rate of monohydroxylation was independent of the saturating gas and, for neutral solutions absorbing all the incident light, increased with increasing initial [a] reaching a constant maximum quantum yield of 0.08 above 2 × 10−2 mol dm−3.
le taux de monohydroxylation est indépendant du gaz produisant la saturation et dans des solutions neutres absorbant toute la lumière incidente, la vitesse augmente avec l'augmentation de la vitesse initiale de [a] approchant un rendement quantique maximum constant de 0.08 au dessus de 2 × 10−2 mol dm−3.
