Abstract

PURPOSE:To obtain the accurate spectrum free from the disturbance absorption which is proper to the solvent by giving correction to the reference spectrum with the correction coefficient with which the coincidence is secured between the sample and reference spectra at the waveform position where no absorption is caused by the sample. CONSTITUTION:The cell containing the sample and the solvent is placed in the sample luminous flux after memorizing the reference spectrum into memory device 85. And change-over switches 82 and 92 are set to the input and output sides of divider 86 each. In accordance with the waveform scanning of the spectroscope, the signal of the sample spectrum received the logarithm conversion is supplied to divider 86 along with the reference spectrum synchronized with the wavelength scanning within device 85, and the ratio between them is obtained to be recorded via output converter 87. The spectrum features nearly 1 of the absorption luminance ratio with the wave number which is free from absorption caused by the sample. Then the spectroscope is set to the wave number with switch 91 turned on, and the ratio of the both spectra at that wave number is registered to coefficient register 84. And switch 92 is set toward the output side of subtractor 87 to carry out the waveform scanning. In this way, the accurate sample spectrum can be obtained.
