In order to obtain more information about the interaction between localized and conduction carrier spin centers in chars and carbons, artificial spin centers (A-centers) were made on sugar and PVDC chars as well as on P-33 carbon black using the oxidation technique developed by Antonowicz.

Samples of P33 carbon black, heat treated in the range 1600"-26OO"C, were studied by E.P.R. The lineintensity, localized and free spins contributions, and g-factor, are examined as a function of residence time at H.T.T. (a few minutes to several hours). The correlation between the g-factor and diama
Carbon films deposited on Pyrex, silica and alumina substrates have free spin concentrations similar to those found for chars. The results of heat treatment show that a maximum in the spin concentration occurs at a heat treatment temperature of about 150ยฐC and that when silica and alumina substrates
