Abstract

Following the work of Haubenreifcer /1/, four types of phosphate groups can be definitely identified in phosphate systems. This is due to well-separated ranges of the 31P-NMR magnetic shielding tensor anisotropy reflecting the different spatial symmetry properties of these different structural units. These groups are: monophosphate groups (Q0), diphosphate groups (Q1), chain phosphate groups (Qz) and branching phosphate groups (Q3), Moreover, a linear correlation could be found of the isotropic value of the 31P-NMR magnetic shilding tensor and the Dietzel field strength of the elements forming part of the secound coordination sphere of the phosphorus.
