Nuclear magnetic resonance (NMR) spectroscopy is an important tool in the structural analysis of both organic and inorganic molecules. Proton NMR spectra can yield information about the chemical or bonding environment surrounding various protons, the number of protons in those environments, and the ...
Spin–Spin Splitting in 1H-NMR Spectra Metin Balci, in Basic 1H- and 13C-NMR Spectroscopy, 2005 Publisher Summary The chapter describes the spin–spin splitting in 1H-NMR spectra and begins with an illustration of the 1H-NMR spectra of ethyl acetate and diethyl malonate. Generally, the spin...
In lyotropic mesophases of decylammoniumchloride the NMR signals of the alkali nuclei 6Li, 7Li, 23Na, 39K, 85Rb, 87Rb and 133Cs solubilized in these mesophases have been observed. The linewidths of the signals are comparable with the linewidths in aqueous solutions. Apart from 6Li and ...

However, we also noticed that after re-calcining the N-doped TiO2in an N2atmosphere at elevated temperatures, the EPR signals of these materials re-emerge and become even larger, implying that more surface oxygen vacancies are regenerated at elevated temperatures (Fig.1b). Thus, the surface oxy...
Proton decoupled 31P in vivo NMR spectroscopy of the human finger flexor muscles was performed during exercise and recovery using a 1.5 T whole-body imager. Predominantly the γ-ATP signal shows a splitting caused by different signal contributions with chemical shifts that vary independently...
