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

Benzoxazines derived from bisphenol-A, formaldehyde, and primary amines were characterized using 13 C solid-state NMR spectroscopy. The two 1,3benzoxazines studied in this work are 2,2Π-(3-methyl-4-dihydro-1,3,2-benzoxazine)propane, (B-m) and 2,2Π-(3-phenyl-4-dihydro-1,3,2-benzoxazine)propane (B-a).
