Experimental Comparison of Solid-state NMR Spectra for Quadrupolar Nuclei Using Various Spin-echo Sequences

Static solid-state NMR spectra for quadrupolar nuclei were compared using various spin-echo sequences, as well as a single pulse sequence. 47/49Ti spectra of TiO2 and 2H spectra of deuterium-labeled poly (methyl methacrylate), PMMA-d8, were assessed as representative half integer and integer nuclear...

Zusammenfassung:Static solid-state NMR spectra for quadrupolar nuclei were compared using various spin-echo sequences, as well as a single pulse sequence. 47/49Ti spectra of TiO2 and 2H spectra of deuterium-labeled poly (methyl methacrylate), PMMA-d8, were assessed as representative half integer and integer nuclear spin systems, respectively. These results indicate that an appropriate spin-echo sequence is essential for obtaining reliable and robust NMR spectra of quadrupolar nuclei.
