Butyl alcohol chemical shifts

Fig. 2. A plot of the chemical shifts of the proton signals (ppm) for the 1,10-phenanthroline complexes of the lanthanides in D2O. The shifts are below the methyl signals of tert-butyl alcohol...

Figure 16 (A) Progression of cITP-NMR spectra displaying acetate chemical shift during passage of interface between focused sample band and TE through RF coil. Each spectrum consists of 8 scans acquired in 10 s. For display purposes, alternating spectra plotted (20-s time resolution). Focused sample band present from 88.83 min to 90.83 min and no longer present at 91.17 min. (B) Acetate and tert-butyl alcohol, full width at half-maximum (FWHM), in Hz and atenolol peak area as a function of run time (min) in cITP-NMR. (Reproduced with permission from Ref. 54.

Butyl alcohol, which was used as an internal standard for chemical shift measurements, has a resonance at 1.2333 ppm downfield from the. sodium salt of 3-(trimethylsilyl)-l-propane sulfonic acid.
