摘要： An absorption spectroscopy apparatus provides an apparatus for analyzing gaseous sample. A measuring section irradiates the gaseous sample with terahertz radiation. An analysis section calculates a concentration of a specific constituent based on a level of absorbance by the gaseous sample. Terahertz radiation at least contains frequency components where the specific constituent shows an absorbance larger than an absorbance by a background constituent. Terahertz radiation at least contains frequency components where a spectrum of absorbance by the background constituent shows relatively flat profile.
