The EPR technique has been developed in this lab top determine the pore size and number distribution in high volatile bituminous coal using nitroxide spin probes I-XIII of different sizes, shapes and reactivity. We have studied pore size and shape distribution in Mary Lee, Black Creek and Pratt coal from Alabama, the Penn State Coals, PSOC Nos. 271, 137 and 669 as well as PSOC-1354 and PSOC-311 and Argonne Premium Coal Samples (APCS) Nos. 3, 4, 5, 6 and 8. These coals were studied because independent SANS, DRIFT and NMR relaxation studies related to pore size and shape distribution have been recently reported which substantiated our results. {sup 14}N and {sup 1}H ENDOR spectra have been obtained for the first time from the nitroxide spin probe-doped Argonne Premium Coal Samples (APCS) Nos. 3, 4, 5, 6 and 8. 8 refs., 1 fig.
