摘要
Quantum yields of nitrogen and hydrogen are recorded for the photolysis at 1849 Å of aqueous solutions of NaCl, KBr, Na 2 SO 4 , NaOH or HCl containing N 2 O or CH 3 OH or both. It is concluded: (i) That the extinction coefficients and quantum yields of hydrated electron formation are—Cl - 3800± 300m -1 cm -1 and 0.43±0.02; Br - , 13000 ± 1000 M -1 cm -1 and 0.34± 0.02; SO 4- 2 , 260 ± 30m -1 cm -1 and 0.71 ±0.04 and OH - , 3600±600 M -1 cm -1 and 0.11. (ii) That k ( e - aq +H + ) = (1.49 ± 0.16) x k ( e - sq. +N 2 O). (iii) That in alkaline solutions a chain oxidation of methanol by N 2 O can occur, (iv) That the application of the Noyes (1955) equation leads to unacceptably large values of the root mean square diffusive displacement.
