Figure 3.

The attenuated total refection-Fourier transformed infrared spectra (ATR-FTIR) of 100 mM half-capped GGG in various D₂O salt solutions. The spectra were collected with the same procedure and the instrumentation employed in Refs. 8 and 15. Peaks in the spectra can be assigned to amide I bands and combination bands of terminal carboxylate group and the amide carbonyl groups.^{8, 16}
