METHOD OF DETERMINATION OF INNER OSCILLATORY TEMPERATURES OF NEUTRAL GAS MOLECULES

摘要

Usage: relates to a controlling but-izmeriGelnoy art. SUMMARY OF THE INVENTION: In the process of ionization is produced T change (oscillatory) temperature molecule substances in range of 450-1200K, relieve temperature zaviIzobretenie relates to the instrumentation engineering and may be used to determine the mass spoktromotricheskogo vibrational temperature of neutral molecules. The purpose of the invention - to increase reliability and determining internal vibrational temperature of neutral molecules. The process is illustrated by Figures 1-6. dence of the relative intensities of the various lines in the mass spectra of analytes, the total ion current, and the relative calibration components. Comparing by changing the ratio of the temperature dependencies of ionic currents in the mass spectra of analytes and gauge temperature dependence of ion currents of the pressure in the test mixture. By comparing the relative intensities of mass spectral lines in the system, and calibration of the temperature dependency determined kachestvennbe distribution of neutral molecules in the vibrational state m. Using the difference of the temperature dependences of the mass spectra, selected operating lines a mass spectrum, the energy of the ionizing electrons, and on the basis of data obtained carried out quantitative analysis of the vibrational state m. Accordingly determined average vibrational energy of the molecule under study and the corresponding e equivalent mean vibrational temperature molecules. 6 yl.
