A possible new application for the "singular value decompositionÏ (SVD) method is described. With the help of SVD, the isotropic NMR shifts of paramagnetic metallorganic compounds of the type (where Cp = g5-Cp 3
Ln AE B cyclopentadienyl, B = neutral base and Ln = lanthanoid) were quantitatively interpreted in terms of dipolar and contact shifts. A brief review of alternative approaches to separate dipolar and contact shifts is given, and the new method based on SVD is shown to be superior on statistical grounds.

**Predominantly covalent Mg—C bonds** are present in dicyclopentadienylmagnesium, as indicated by ^25^Mg‐NMR spectroscopy. The large range of the ^25^Mg chemical shifts (ca. 200 ppm) also facilitates clarification of other controversial bonding behavior. For the investigation of Schlenk equilibria [
The polarization transfer method DEPT (distortionless enhancement by polarization transfer) was employed to set up a quantitative method to detect olive oil adulteration by seed oils, in particular soybean oil. The DEPT pulse sequence promotes the transfer of polarization from "concentrate spins = 1
