Web(19) is often called a crude adiabatic basis. Compare Eq. (28) with the adiabatic form of the time-independent Schr odinger equa-tion in Eq. (14). Both describe the same physics, but instead of derivative couplings (T(1) mn and T(2) mn) between the potential energy surfaces of the di erent electronic states, we now deal with coordinate ... WebThe adiabatic potentials for (SiH)3+ [ 1 Σ +, 1 Π, 1 Δ] are displayed as a function of R in Figure 10.1. The molecular orbitals used to construct the electronic states are dependent on the origin of electronic coordinates. A near crossing can be seen between 3 1 ∑ + Si 2+ (3p 2 1 D o) + H + and 4 1 ∑ Si 3+ (3s 2 S) + H (1s) at R = 11.745 ...
