Signal peaks $\mathsf{\Delta }s$ evaluated at the three characteristic wavenumbers ${\nu }_1=1034 {\mathrm{cm}}^{-1}$ (a), ${\nu }_2=1063 {\mathrm{cm}}^{-1}$ (b), and ${\nu }_3=1078 {\mathrm{cm}}^{-1}$ (c) originating from pure water for each of the three measurement cycles (gc = glucose cycle, fc = fructose cycle, and mc = mixed cycle).
