FRIR-ATR spectrometry has been used to monitor the aqueous reactions of compounds without distinct chromophores in ultraviolet and visible regions. For example, hydrolysis reactions of <TEX>${\alpha}$</TEX>-cyclodextrin and <TEX>${\gamma}$</TEX>-cyclodextrin in acidic aqueous solution were studied. FTIR-ATR method has been used for the monitoring of cyclodextrin hydrolysis in 1.0 M. 0.5 M, and 0.1 M HCl solutions, respectively. We also found that the hydrolysis of <TEX>${\alpha}$</TEX>-cyclodextrin produced glucose, but the hydrolysis of <TEX>${\gamma}$</TEX>-cyclodextrin proceeded further to give more fragmented products than glucose.
