โฆ Synopsis
Comparison of X-band (9.1 GHz) and Q-band (35.2 GHz) electron paramagnetic resonance (e.p.r.) spectra of oil shale. shale oil, and spent shale indicates that the organic free radical signal observed in all three types of samples is a composite spectrum.

E.s.r. spectra of several oil shales from eastern and western USA have been measured at 9 and 25 GHz. The spectra of the western shales were similar to previously reported spectra and consist of a Mn'+ signal and a featureless organic signal. The eastern spectra consist of a V4+ signal and a complex
Shale oil recovered from Fischer assays of fresh and artificially weathered oil shales have been compared using 'H and 1 3C nuclear magnetic resonance spectroscopy and elemental analyses. Rundle, Julia Creek and Green River shales were exposed to air at 100ยฐC for 60 weeks to simulate either geologic
