Abstract Using the pulse radiolysis technique the OH adducts of cytosine, 5-methyl cytosine and 2'-deoxycytidine were investigated in alkaline N2O saturated aqueous solutions. Ab-sorption spectra were recorded and their change with time was correlated with the change in conductivity. An OH -induced reaction (1.4·108)·mol-1·s-1) was observed with OH adducts of cytosine and 5-methyl cytosine leading to radicals (pK=10.3), the G-values of which were 3.2 and 1.6 respectively (conductivity measurements). These intermediates were assigned to the C-5 OH radical adducts. After completion of the free radical reactions (2k = 6 · 108)·mol-1·s-1) the resulting product mixture showed pK-values of 8.3 (cytosine, G=0.6), 10.5 (5-methyl cytosine, G=0.8), 10.7 (cytosine, G=1.5; 2′-deoxycytidine, G=1.5) and 12.4 (cytosine, no G-value, determinable with optical detection). Ammonia, which is a product measured after γ-radiolysis of all the three compounds investigated (G(NH3) = 0.6 ± 0.1), is not released within 15 ms after the pulse.

AbstractBased on the recent findings about the ability of sexual hormones to emit electrons (eHighest purity adrenaline (ADR) and chemicals were used for preparation of aqueous solutions (pH ∼7.4). The excitation of ADR in singlet state was achieved by irradiation of airfree aqueous solution with monochromatic UV light at λ=254 nm. The emitted “solvated electrons” (eIt was found that Q(e

Recently the UV photoreduction of graphene oxide in aqueous solution received considerable attention. Here we show that the photoreduction is not governed by the reaction of GO with solvated electrons originating from water.
