In this paper a computer interpretation program used for infrared spectral interpretation and library search is presented.The chromatographic peaks can be rapidly and correctly identified by the interpretation program which is based on the infrared characteristic absorption frequency, chromatographic retention index and results for the library search. The absorbance spectra of the chromatographic peaks and the closest reference spectra in the library may be plotted for the advantage of check. When the closest reference spectra are not found in the library, the interpretation program can also accurately identify the unknown compound.Satisfactory interpretation results are obtained in analysis of a wash oil of coal tar by using this interpretation program.

Infrared spectroscopic analysis was used in the study of sulfoaluminate cementclinker, showing that the clinker minerals have their characteristic IR absorption bands.1098cm~(-1) or 641cm~(-1) absorption band and 520cm~(-1) band are suggested by the author for theidentification of C_4A_3S and β-C_2S respectively.Results show that IR is an effective meansfor the study of sulfoaluminate cement clinker both qualitatively and quantitatively.Besides, IR evidence shows that C_2S in sulfoaluminate cernent exists as a solid solutionand that small amounts of other elements are taken up by ettringite in the cementpaste to form solid solution. Characteristic absorption bands are also given in this paper for different hydratedphases of sulfoaluminate cement.The process of hydration of sulfoaluminate cement isdiscussed, based on IR spectra of cement pastes for different ages.
