Abstract: (Graph Presented) We report a sum frequency generation (SFG) spectroscopy study of D-glucose, D-fructose and sucrose in the C-H stretching vibration regime. Wetting effect on the SFG spectra was investigated. The SFG spectrum of D-glucose changed from that of α-D-glucose into those of α-D-glucose monohydrate by wetting. The SFG spectra showed evidence of a small change of β-D-fructopyranose into other anomers by wetting. SFG spectra of sucrose did not change by wetting. Assignments of the vibrational peaks in the SFG spectra of the three sugars in the dry and wet states were performed in the C-H stretching vibration region near 3000 cm-1.
