However, hydrogens of external alkynes resonate at lower frequency than vinylic hydrogens at appear at ppm range. Shift reagents and solvent induced shifts. Determine the relative area of each signal, as compared with the area of other signals, as an indication of the relative number of protons producing the signal. Nakanishi, Ed.
