## Abstract The chiral phosphorus derivatizing agent (CDA) 1 was prepared from optically pure (S)โ__1,1โbisโ2โnaphthol__. It was first used in the determination of the enantiomeric excess of chiral alcohols and amines by means of ^31^P NMR spectroscopy. It showed that, for the chiral aromatic alcoh

## Abstract A description is given of an ergometer made of nonmagnetic materials which fits into a standard whole body MR magnet. __T__~2~โweighted images show that exercise is highly specific for quadriceps muscles. The ergometer permits the noninvasive study of __T__~2~โrelated changes in the pro
