Proton T2 relaxation and n.m.r.
The purity of HMDSO was checked by proton, C13, and Si29 NMR spectroscopy.
The O H proton (D2O exchangeable) is observed at 12.40 ppm as a singlet peak.
Realistic proton density/T1/T2 values were also defined for the MRI simulation.
Experimental results are presented as 2D plots with axes defined by proton (1 H) and carbon (13C) chemical shifts.
Proton (1H) lineshapes and spin-lattice relaxation times were measured as a function of temperature.
Proton (1H) line shapes and spin-lattice relaxation times were measured as a function of temperature.
In NOESY experiments, interglycosidic NOE contacts were recorded between Xyl2 anomeric proton (4.406 ppm) and the signal at 3.678 ppm of proton 4 of Xyl3 and between anomeric proton signal at 4.37 ppm of Xyl3 with the signal at 3.667 ppm, proton 4 of Xyl4.
Proton 1D spectra were measured unlocked with 128 scans and 32k resolution over a spectral width of 15 ppm.
In the present study, the computational conditions and procedures employed in previous studies on other ion [9], [10] and proton [11], [12] channels were consistently used.
