We use Sinc DVR method to calculate the electronic properties of SM model including the adiabatic electronic eigenstate, dipole moments and derivative coupling. The grid of DVR is uniform with spacing ∆x = 0.147 in the range [-22, 22] (a.u.). In the exact quantum simulation case, we also use the same method to solve the TISE 61 with finer grid points for nucleus ∆x = 0.016 in the range [-8, 8]. To test the convergence of grid points, we doubled the number of grid points and the results were identical.
