Abstract
The elusive protonated ozone ion (O3H+) was detected in mass spectrometric expts. using Fourier transform ICR. In these expts., O3 was protonated by strong acids for example, H3+, KrH+, XeH+, and CH5+. The hitherto exptl. unknown proton affinity of O3 was evaluated by a bracketing technique and is 148 ± 3 kcal mole-1 at 298 K, in excellent agreement with a value detd. in a recent theor. study of the O3/O3H+ system, which was 148 kcal mole-1 at zero temp. (∼149.5 kcal mole-1 at 298 K).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
