Abstract

The paper describes high resolution microwave spectrometry of gases in the millimeter region using the White type cell. The optical system has been improved by repla­cing Teflon lenses with two toroidal mirrors. The function of this apparatus was tested by measuring the isotopologues of CO. Thus the configuration with a 48-m optical path was obtained and the measurement sensitivity was enhanced by 33 % compared with the previous set-up.
