Rundle shale (Queensland, Australia) was pyrolysed at 12.5 K min-' to 35&5Oo"C for 10-240 min. The structures of the liquid products and pyrolysis residues were investigated by a number of n.m.r. spectroscopic techniques including cross-polarization and dipolar dephasing. N.m.r. provided a simple me
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.
