Both the it- and st-oligomers were found to take the extended, all trans conformation in solution, from the observed patterns of the 4JHH long-range correlation peaks in the 1H COSY spectra. The 13C-T1 values of the it-hexamer were larger than those of the st-hexamer for any carbon ...
This study attempts the application of 1H NMR spectra as a characteristic of commercial herbal preparations. 1H NMR spectra of four herbal preparations hav
