METHOD FOR DEFINITION OF THE ELECTRON AFFILITY MOLECULES OF POLYCYCLIC AROMATIC HYDROCARBONS

摘要

FIELD: physics.;SUBSTANCE: invention relates to physical measurements and relates to a method for determining the electron affinity of polycyclic aromatic hydrocarbon molecules. Method includes recording and studying the absorption spectra of samples in ultraviolet and visible regions of the spectral range. Electron affinity is determined by a relative empirical autocorrelation parameter μ, which is the ratio of autocorrelation functions, calculated from the electronic spectral range. Electron affinity is determined by the formula: EA = 1.503-0.19134*μ, where - relative empirical autocorrelation parameter, where - integral of the autocorrelation function in the ultraviolet region, - integral of the autocorrelation function in the UV and visible regions of the spectral range.;EFFECT: technical result consists in providing the possibility of applying the method to complex molecular, multicomponent and metastable substances, increasing the accuracy and speed of measurements.;1 cl, 1 tbl
