The energetics of the benzoyl radical have been studied by photoacoustic calorimetry. The value obtained for D[PhC (0)-H]. 371? 11 kJ mol-' (89 + 3 kcal mol-' ), agrees with an early result derived from iodination kinetic experiments and does not support a recent suggestion that the radical is reson

## Abstract The recombination of c‐C~5~H~5~ with H‐atoms has been studied behind reflected shock waves. The obtained rate coefficients are almost independent of temperature and were found to be __k__~rec~ = 2.6 × 10^14^ cm^3^ mol^−1^ s^−1^ for pressures around 2 bar in the temperature range between
