THEORETICAL AB-INITIO CALCULATIONS OF THE ELECTRON-AFFINITY OF THYMINE

It was determined in ab initio calculations that an electron can attac h to thymine, forming a stable anion. The electron is attached predomi nantly to the positive end of the molecular dipole moment; however, so me contribution from the covalent character is also present. The adiab atic electron affinity for this process is estimated to be only 0.088 eV.
