β¦ Synopsis
The recent report of the identification of the H30 radical is shown to be erroneous. ESR studies of aqueous solutions enriched to over 90 atom% in 170 provide no evidence for the H30 radical. The spectrum originally assigned to H30 is probably due to the methyl radical.

n-C3H70N0 was photolyzed with 366 nm radiation at -26, -3,23,55, 88, and 120Β°C in a static system in the presence of NO, Oz, and N 2 . The quantum yields of C2H5CH0, C z H 5 0 N 0 , and CH3CH0 were measured as a function of reaction conditions. The primary photochemical act is and it proceeds with
The results of INDO calculations do not support the discovery of the I-i30 free radical\_ Recently Martin and Swift [I ] came to the conelusion that they had clearly demonstrated "the first direct and unequivocal evidence for the hydronium radical" H,O. Their H30 spectrum is characteristic of a free

The reaction of CF3 radicals with Ha0 (D20) has been studied over the range of 533-723 K using the photolysis and the pyrolysis of CFJ as the free radical source. Arrhenius pa- rameters for the reactions where X = H or D, relative to CF:j radical recombination are given by log kHlkf'2 = (5.12 f 0.1
