Chiral NMR recognition of terpenic and similar hydrocarbons by Ag(fod) and optically active lanthanide shift reagents is descnloed. Twenty-four 'H signals of eight compounds and, as a first report in the literature, eleven I3C signals of three compounds were split into signal pairs due to the respec

## Abstract High field high resolution ^13^C NMR spectroscopy allows the quantitative determination of a mixture of the four diastereomers in racemic Ξ±βtocopherol.
Absolute configuration and enantiomeric purities of some hydroxyketones and diols of spiro[4\_4]nonane and 2,2'-spirobi-indan can be simultaneously determined by use of MTPA derivatives and a lanthanoid shift reagent.
