The first ionization potentials Ip of aliphatic amines, alcohols, ethers, thio-alcohols and thio-ethers can be expressed as the function of atomic electronegativity X~z~O (z=N, O, or S atom), the atomic charge q~z (z=N, O or S atom) and the Polarizability Effect Index (PEI) of alkyl group: Ip(eV)=4.4851+3.0727X~Z~O+7.1702q~z-1. 3949∑PEI.

Key words: POLARIZATION EFFECT, IONIZATION ENERGY, ALIPHATIC AMINES, ELECTRONEGATIVITY, ALIPHATIC COMPOUNDS, ORGANIC COMPOUNDS, ALIPHATIC ALCOHOLS, ETHER
