Dose Effects

For carefully purified concentrated aqueous solutions of N 2 0, G (N 2 ) is initially greater than the steady state value of 3.0 and G (O 2 ) less than the steady state value of 1.45 when G (H 2 ) = G (H 2 O 2 ) = 0. For very dilute solutions G (N 2 ) is small, independent of dose rate and decreases with increasing dose and decreasing [N 2 O], while G (H 2 ) is initially > 0.45, independent of dose rate and decreases with dose. The high initial G (H 2 is not due to organic or other impurity and is thought to arise either from bimolecular reaction of e aq − . and H within a spur or track or from unimolecular decomposition of the solvated electron either to H 2 + O - or H + OH - or from a combination of both. The dose effects are attributed to competitive scavenging of e aq − . by H 2 O 2 as the latter is produced.
