N2 - Reactions of C2H{radical dot}+2 with methanol, chloroacetonitrile and ethyltrifluoroacetate were studied in a selected-ion flow tube in order to bracket the proton affinity of the C2H{radical dot} radial. The proton afinity PA(C2H{radical dot}) was measured as 181.6 ± 1 kcal mol-1 at 298 K. A thermochemical cycle leads to the bond energy D0 (C2HH) = 129.3 ± 1 kcal mol-1. This value is in good agreement with previously published data and corrects an ealier published value from this laboratory.
