    Notes: Knowledge of the granulometric behaviour of dispersed systems is vital for a full and complete characterisation. Despite the variety of methods and devices which have been developed for this purpose, difficulties frequently arise in the practical determination of particle size distribution. In this paper it is shown, by means of examples, how measurements for surface modified and porous particles can be influenced by the behaviour of the material, and which approaches exist to obtain accurate values by taking this into account.

    Notes: The first phosphines based on the benzo-7-phosphanorbornene system have been prepared and found to have extremely deshielded 31P nuclei. The phosphine with a P-tert-butyl group gives the most downfield value (δ +152.5) ever recorded for a tertiary phosphine. The lone-pair orientation in phosphines controls the magnitude of 2J (PC) and 3J (PC), and these effects were used to determine stereochemical features of the phosphines. These compounds were formed by HSiCl3—pyridine reduction of the Diels - Alder adducts of isophosphindole oxides with norbornadiene. 13C NMR was also used to confirm the assignment of these phosphine oxides.
