Morse Potential Energy Curves Cytosine, Thymine

MORSE POTENTIAL ENERGY CURVES FOR THYMINE AND CYTOSINE 311... 

Figure 12.9 Morse potential energy curves for thymine in the N—H dimension calculated from E and data in Figure 12.5 [7, 28]. The molecular anion formed at 0.2 eV comes from the vertical transition to the A curve, while those at 0.8 eV come from the B and C curves and the one at 6 eV comes from the D curve. There is no peak at 1.5 eV, as occurs in cytosine. The parameters are given in Table 12.8.
