## Abstract Siliconβ29 NMR spectra were obtained for more than 20 aqueous alkaline silicate solutions containing methanol. A signal assigned to CH~3~OSi(OH)~3~ or one of its deprotonated congeners was studied in detail for the first time for the solution conditions involved. Its appearance was moni
The photochemistry of aqueous solutrons of iodide and bromide is investigated in the presence of high concentrations (2 x 10m2 M < C c 1.2 M) of nitrous oxide. In the iodide system, the photo-oxidation yfeids depend markedly on [N20]. The effect is attributed to the scavenging of solvated electrons
