Spin lattice relaxation times in both the lab and rotating frame, have been measured for deuterons (2 H) in a number of unsonicated dispersions of 1,2 dipalmitoyl phosphatidylcholine in D 20 over a range of resonant frequencies from 13 MHz to 1 MHz for temperatures from -20Β°C to 65Β°C. The proton (1
A 'H-n.m.r. study of the 0-polysaccharides from different types of Shigelh flexned has been performed. With the aid of 2D-n.m.r. techniques, namely, J-resolved, spin-spin correlation, and NOESY experiments, most of the structural features of these polysaccharides could be deduced. Sequences could ge
