PROBLEM TO BE SOLVED: To provide a spectrometer, a spectrometry, and a spectrometric program capable of reducing an effect of a stray light occurring in the spectrometer. SOLUTION: The spectrometer 1A includes an integrating sphere 20 internally containing a sample S, a spectroscopic analyzer 30 dispersing a measurement object light from the sample S to acquire a wavelength spectrum, and a data analyzer 50. The analyzer 50, comprising an object domain setting section for setting a first object domain corresponding to an excitation light in the wavelength spectrum and a second object domain corresponding to luminescence from the sample S; and a sample information analyzing section for calculating a luminescent quantum yield of the sample S; calculates a measurement valueΦ<SB>0</SB>of the luminescent quantum yield from results of reference and sample measurements, and using coefficientsβandγassociated with the stray light in the reference measurement, calculates an analysis valueΦof the luminescent quantum yield less affected by the stray light, by a formula ofΦ=βΦ<SB>0</SB>+γ.
