Proton nuclear magnetic resonance ('H n.m.r.) has been used to measure changes in the water-binding capacity of bed-moist brown coal lithotypes subjected to heat treatment. A rapid reduction in the coalwater interaction was found to occur at treatment temperatures > 420K. A Pale lithotype was found
The hypothetical average structures of two coal liquid asphaltenes were determined using solid state 13 C NMR and 1 H NMR data. From the 1 H NMR data average molecular structural parameters were obtained using the Brown-Ladner method to get a general average structure. From the solid state 13 C NMR
