Spin-orbit coupling elements with TDDFT and TD-DFTB.
PySOC is a program for fast and flexible computation of spin-orbit coupling matrix elements. In the current version, it works with TDDFT (Gaussian) and TD-DFTB (DFTB+).
Getting the code: PySOC can be obtained free of charge by contacting Dr. Xing Gao at email@example.com. Please, include your name and affiliation.
