The R prism is brought into close contact with the sample, the sample is irradiated with infrared light through the ATR prism, and the light emitted from the ATR prism is spectroscopically measured. When the ATR prism is placed in close contact with the sample and infrared light is incident on the ATR prism, if the infrared light is incident on the prism at a certain angle or more due to the relationship between the refractive index of the ATR prism and the sample, the infrared light will be emitted from the ATR prism. Total reflection occurs at the contact surface between the ATR prism and the sample. When infrared light is totally reflected at the contact surface between the ATR prism and the sample, the infrared light seeps out a short distance toward the sample, and if the sample absorbs the infrared light at that time, the reflected light is attenuated. , the absorption spectrum of the sample can be obtained.
