## Abstract The ^31^Pο£Ώ^31^P and ^13^Cο£Ώ^31^P coupling constants in 1,6βdiphosphatriptycene have been obtained from analysis of its proton decoupled ^13^C n.m.r. spectra. More accurate data, however, resulted from simultaneous analysis of the proton decoupled ^13^C spectra and ^31^P(^13^C) satellite
Crystal structures of two 1,6-anhydro-beta-maltotriose derivatives, 1,6-anhydro-beta-maltotriose nonaacetate and 6"-bromo-6"-deoxy-1,6-anhydro-beta-maltotriose octaacetate, have been determined. Both structures are isomorphous and belong to the orthorhombic system, space group of P2(1)2(1)2(1), with
