PROBLEM TO BE SOLVED: To provide an infrared spectroscopic device and an infrared spectroscopic measurement method capable of easily analyzing an infrared absorption spectrum by an ART method.SOLUTION: A correction formula calculation unit 51 has stored therein a standard transmission absorption spectrum and a standard total reflection absorption spectrum. A spectrum calculation unit 52 calculates, by standardizing a sample to be measured, a corrected transmission absorption spectrum that corresponds to a transmission absorption spectrum for the case where the sample is measured by a transmission method, said sample being standardized by the depth of permeation that is calculated on the basis of the standard transmission absorption spectrum and standard total reflection absorption spectrum, assuming that the intensity of the total reflection absorption spectrum measured by a total reflection absorption method is the depth of permeation of an infrared ray into the sample as it is totally reflected. |
