Study of Substituent Effects and Correlations of Molecular Ionization Energies of Some Organic Compounds

Muayed Khaleel Ibrahim

Abstract: Ionizing energies of the gas phase of various organic compound such Amines, alcohol, ethers, thiol, aldehydes, ketones, carboxylic acids and esters. Has been measured to explore any arrangements and linkages within each group and any possible reciprocal links between groups of similar compounds. It has been found that there is a common pattern of mutual relations and correlations regardless of the type of functional group, and that ionizing energies within similar groups are interrelated depending on the number of carbon atoms and alkyl groups involved. The identification of these interlinkages and linkages has helped to exactly estimate of ionizing energies of different sets of analogue compound.
