Low-energy Electron Collisions with Gas-phase Thymine Molecule

Abstract

The paper presents an investigation of the negative ion formation of the thymine (T) molecule. The formation of negative ions by electron impact of this molecule is measured. The quantum mechanical investigations are performed to calculate the electron attachment cross section, the force constants, the resulting vibrational frequencies and intensities. The absorption spectrum and their nature are investigated too. The obtained results allows us to foresee the mechanism of production of the [T-H]- ion and explain the origin of some features in the experimental negative ion formation of the thymine molecule.http://dx.doi.org/10.5755/j01.ms.17.3.601
