The asphaltene of the Athabasca bitumen exhibits a single, structureless e.s.r. signal at a g-value of 2.0032 with an intensity corresponding to approximately one free spin per ninety molecules. From the temperature dependence of the absorption it is concluded that absorption is due to stable polycy

## This paper presents the results of electron spin resonance measurements on several types of stable aromatic free radicals suspected as intermediates in carbonization. The radicals studied include phenalenyl, 1-methylphenalenyl, 1-phenylphenalenyl, fluorenyl, 9-phenylfluorenyl, and biphenyleneal
## ABSTRACTS above 650"HTT, and no resonance reappearing above that (checked up to 1600ยฐC). The temperature dependence is for PVC exactly Curie type, so is also for the sugar chars, however, with a deviation gradually showing up above HTT of 700ยฐC. It is believed that this deviation is due to incr
