Corrigendum: Vibrational enhancement of positron affinities for nonpolar carbon dioxide and carbon disulfide molecules: Multi-component molecular orbital study for vibrational excited states

Abstract

To demonstrate the binding of a positron to nonpolar CX2 (X = O and S) molecules, we have estimated the vibrational averaged positron affinity (PA) values for the harmonic asymmetric stretching vibrational coordinate with the multi-component molecular orbital method. A positron can be attached at higher vibrational excitation levels, and vibrational averaged PA values become greater as the number of vibrational quantum number increases. The resultant PA values of carbon disulfide (CS2) molecule are greater than those of CO2, which is consistent with the corresponding property such as infrared (IR) intensity and polarizability of the parent species. © 2012 Wiley Periodicals, Inc.
