The experimental paramagnetic contributions T −1 ip = T −1 i(obs) − T t-1 i (blank) are reported in Table I for H 4 of the imidazole moiety at different [Cu ++] tot/ [His] tot ratios. In these conditions CuA 2 (His = H 3A) is almost exclusively present in solution [...

Proton NMR relaxation times (T2 T1, and T1ϱ) and absorption spectra are reported for the compounds H1.71MoO3 (red monoclinic) and H0.36MoO3 (blue orthorhombic) in the temperature range 77 K < T < 450 K. Rigid lattice dipolar spectra s... CT R.,Slade,and,... - 《Journal...
Table1shows that the activation energy values are higher for [C2MIM][OOct] than those of [C2MIM][OAc], regardless of the experimental technique used. The higher molecular weight of [C2MIM][OOct] makes the translational motion required for both diffusion and viscosity more difficult to activat...
Proton Spectra(Table1).A sample of the solvent,containing1μL of TMS,1was fit run on its this spectrum we determined the chemical shifts of the solvent residual peak2and the water peak. It should be noted that the latter is quite temperature-dependent(vide infra).Also,any potential ...

NMR Solvent Peaks is a conveniently-searchable version of the ungainly table of NMR data most organic chemists keep a copy of nearby. Instead of searching through the table for a peak near your unidentified peak, just enter your solvent and the peak's multiplicity and location and you'll have...
