Choosing of the best experimental conditions with an absorption spectrometer

Abstract

A test of quality determining the accuracy of the measurement of the wave-numbers of absorption lines is proposed. The research of its maximum enables the choice of the best conditions of experiment according to the shape of the absorption factor of the line and according to the resolving power of the spectrometer that is used. The pressure of the absorbing gas and the distance covered by the light in a « White » cell can be deduced from the system of the graphs to be seen in the paper.
