The complete analysis of the 1H, 13C, 15N NMR spectra of iminopyrophthalone demonstrates that the solution structure of the molecule must be described as a protonated iminocompound. 13C-CP/MAS spectroscopy proves that the solid state structure of α-PPH and IPH are equivalent to the solution structure.

The 31P suspension NMR spectra o f silica-immobilized bifunctional phosphines and their di- and tricarbonylnickel complexes were recorded using conventional high resolution NMR equipment. The practical advantages of suspension NMR spectroscopy, as compared to 31P CP/MAS NMR spectroscopy, are discussed. General tendencies are demonstrated: The suspension NMR signals become broader with increasing solvent viscosity and decreasing solvent polarity. Phenyl groups as spacers lead to broader resonances than alkyl chains. The linewidths increase in the case of chelation.
