On the existence of the hypervalent H3O, H2DO, HD2O, and D3O radicals
Abstract
The existence of oxonium radicals on the microsecond time scale has been up for much debate, and strong isotope effects have been reported. Here we show that H3O, H2DO, HD2O, and D3O all have subnanosecond lifetimes when they are formed in charge-transfer collisions between oxonium cations and cesium.
A kinetic isotope effect on hydrogen versus deuterium loss from HD2O was found to be 2.4, similar to that found in dissociative recombination of HD2O+ and for dissociation after electron transfer to HD2O+ from potassium.
