## Abstract An analysis of the ^1^H and ^13^C spectra of 1‐azafluorene has been carried out using computer calculations and homo‐ and heteronuclear double resonance techniques. The ^4^__J__, ^5^__J__ and ^6^__J__ long‐range coupling constants of the 9‐CH~2~ group protons with the protons of the pyr
o-Benzenediazonium carboxylates couple with methylene-active compounds to yield hydrazo derivatives with high purity. The 'H and 13C NMR data of eleven such products are presented and analysed. The predominance of the hydrazo over the azo form is consistent with accepted criteria. Furthermore, evide
## Abstract We show how high‐resolution magic angle‐spinning NMR spectroscopy can be used to characterize ^13^C‐labeled saccharides that have been prepared using solid‐phase synthesis techniques while they are still bound to a solid‐support resin. With the use of ^13^C‐labeled glucose as the starti
Solid poly[(R)-3-hydroxybutyric] acid was examined by high-resolution 13C MAS NMR, differential scanning calorimetry and infrared spectroscopy. The 13C methyl group resonance consists of three components: the rigid amorphous phase, the crystalline phase and the mobile amorphous phase. Spectral decon
## Abstract Magic angle spinning (MAS) ^13^C NMR was employed to investigate seeds. By combining single pulse excitation (SP) and cross‐polarization (CP) experiments, we showed that both liquid and solid domains of plant seeds (__Arabidopsis thaliana, Lactuca sativa__ and __Pisum sativum__) can be
