✦ Synopsis

The ::C-and 3:P-NMR ~pectra and DSC thermograms of unsonicated dispersions consisting of phospholipids of varying methylation stages of the pzopanolamine head group were investigated. Methylation of the head grot, p was accompanied by a corresponding reduction in the phase transition temperature~ In the liquid crystalline state the 3:P-ani~tropy of the chemical shift is about equal for all studied compounds, demonstrating that the motion of the phosphate group is not influenced by modifications of the propanolamine group.

The phase transition in bicyclononanone, C 9 H 14 O, has been examined using differential scanning calorimetry, variabletemperature vibrational spectroscopy, and proton spin-lattice relaxation time measurements. The high-temperature phase is disordered and the low-temperature phase either has an ort
