Role of Non-Statistical E ect in Deciding the Fate of HO • 3 in the Atmosphere
Abstract
HO • 3 has been postulated as a reservoir for OH • in various atmospheric reactions. Under collision-free conditions, the experiment recommends that the lifetime of this species should be more than one μ s. Interestingly, the binding energy of HO • 3 is estimated to be ∼ 3 kcal mol −1 by recent experimental as well as theoretical works. The value of the binding energy suggests that the lifetime of HO • 3 should be in the picosecond range, and with this lifetime, HO • 3 can not act as a reservoir for OH • . In the present work, using on-the- fly semiclassical dynamics, we argue that even with low binding energy, the lifetime can be high if one incorporates the non-RRKM effects in estimating the lifetime of HO • 3 .
