Investigation of Gaseous Chlorine Compounds by X-ray Absorption Spectroscopy

摘要

We measured the x-ray absorption spectra of gaseous chlorine, Carbon tetrachloride, and Ethylene chloride. The samples were mixed with Helium at approximately 1000 ppm concentration and flowed through the detector/sample cell. This consisted of a cavity in a 1.3 cm Lucite block covered Lucite block covered from and back with 6 micrometer aluminized Mular windows. At the center was a thin electron-collecting grid of Ni mesh. The windows were connected to -45 V while the positive battery terminal was connected to the ground of the electrometer.
