Using radiolysis of chloroform /CHCl3/, 3,5-dibromo-4-oxo-2,2,6,6-tetramethyl-piperidin-1-oxyl /1/ is oxidized to its corresponding oxoammonium bromide /3/. The mechanism is a one electron oxidation forming the oxoammonium ion /3/ which is stabilized

A preliminary description of a convenient method for the reduction of nitroxide spin labels by a radiolysis technique is described; the main advantage of this procedure is the ease with which nitroxides are converted to the corresponding non-paramagn

The transient spectrum obtained in pure liquid hydrazine shows a broad absorption extending from 500 to 1100 nm which has been attributed to the solvated electron; its maximum wavelength is located beyond 1100 nm. A small uv band is also found, proba
