In this paper, we couple a numerical kinetic-energy operator approach to the direct-vibrational self-consistent field (VSCF)/vibrational configuration interaction (VCI) method for the calculation of vibrational anharmonic frequencies. By combining th... Read More about Fast vibrational configuration interaction using generalized curvilinear coordinates and self-consistent basis.
