Abstract
The absorption cell consists simply of a pyrex tube with a polystyrene lens and microwave horn at each end to couple to the standard microwave components. The lenses also serve as the vacuum windows. The attenuation at 8.5 mm. wavelength is 3.4 db. for a 250 cm. cell. Since there are no metal surfaces, this type of cell is very suitable for the investigation of reactive molecules. It can readily be employed in a high temperature microwave spectrometer for the investigation of corrosive substances with low vapor pressures, or in a Zeeman modulation spectrometer for the study of free radicals.
