Linear Synchronous Transit , Local

Figure 12.10. Potential-energy functions of the S0 state, the locally excited 1 hit states of guanine and cytosine, the lowest1 rnr state, and the tt-jt charge-transfer state of the WC conformer (a), the conformer B (b), and the conformer C (c) of the CG dimer. The PE functions have been calculated along the linear-synchronous-transit proton-transfer reaction path from the S0 minimum to the biradical minimum. Insets show the potential-energy function of the locally excited 1mr state of guanine calculated along the minimum-energy path for stretching of the NH bond...
