Figure 5.
VCD spectra of 11 mM VEALYL after the pH of the solution has been lowered from 7 to 2.5, with tentative assignments indicated. The increasing signal strength at ∼1621 and 1635 cm−1 indicates that chiral structures are formed that are of the order of 6 μm (the wavelength equivalent of ∼1650 cm−1).
