Summary: | Deconvolution of the Fourier transform infrared (FT–IR) spectrum of
α-
d-glucose in the 1500–500 cm
−1 range has been carried out and the deconvolution results have been compared with IR and Raman spectra of the above compound recorded at room and a low temperature as well as with the data of normal coordinate analysis of the
α-
d-glucose molecule in the crystalline state. It is shown that deconvolution of the IR spectra recorded at room temperature permits separating absorption bands observed in the vibrational spectra obtained by using cooled samples. Also, as a result of deconvolution, it is possible to improve the resolution of individual components of complex absorption bands without frequency shifts characteristic of low temperature spectra, which can be used for analytical purposes. The results of IR spectrum deconvolution are in good agreement with the data of normal coordinate analysis of
α-
d-glucose in the crystalline state. |
