## Abstract A two‐component extension of the seminumerical procedure for the calculation of the Hartree–Fock (HF) exchange matrix recently presented by Neese et al. (Chem Phys 2009, 356, 98) was implemented into the program system TURBOMOLE. It is demonstrated that this allows for efficient self‐co
For calculating the transition amplitude, especially the density matrix, important for the quantum-mechanical chemical reaction dynamics, the stochastic path-Ž . integral method SPIM was developed and then realized by solving the stochastic partial Ž differential equation in use of a corresponding s
