## Abstract The 270 MHz n.m.r. spectra of phosphoserine (PSer) have been measured and completely analysed for seven pD values. The resulting vicinal coupling constants ^3^__J__(HΞ±HΞ²) and ^3^__J__(PHΞ²) are used to discuss the conformations of PSer with respect to the (HΞ±)ο£ΏCΞ±ο£ΏCΞ²ο£Ώ(O) and (CΞ±)ο£ΏCΞ²ο£ΏOο£Ώ(P)
The 13C-n.m.r. signals of the heptitols in aqueous solution, and of their acetates in chloroform solution, have been assigned by the use of specifically deuterium-substituted compounds. From these spectra, the preponderant conformation of each heptitol has been determined, particularly by comparison
