Figure 5. Chiral SFG spectra of LK7β deposited on glass slides.

Figure 5.

The samples are prepared using solvents of (a) H2O, (b) D2O, (c) H218O, and (d) D218O. Each spectrum exhibits a minor and a major vibrational band. The 18O substitution shifts the minor peak in the H2O spectrum and both major and minor peaks in the D2O spectrum by about 10 cm−1, confirming water contributions to the chiral SFG spectra.
