PROBLEM TO BE SOLVED: To provide an absorption spectrum analyzer capable of setting a base line of an absorption spectrum without using a calibration curve, to provide a method of setting a base line of an absorption spectrum of a substance, and to provide a computer program. ! SOLUTION: Wave numbers at a plurality of peaks of actual measurement values of an absorption spectrum measured by infrared spectroscopy with the sun as a light source are specified, and transmission factors of logical values of the absorption spectrum corresponding to the plurality of specified wave numbers respectively are specified, and the specified transmission factors are interpolated to generate a logical value interpolation line. Further, wave numbers at a plurality of peaks of logical values of the absorption spectrum are specified, and transmission factors of actual measurement values of the absorption spectrum corresponding to the plurality of specified wave numbers respectively are specified, and the specified transmissio |
