The EPR (ESR) g-tensor, hyperfine interaction (A-tensor), nuclear quadrupole interaction (Q-tensor), and zero-field splitting (ZFS, D-tensor) can be calculated. Effects due to spin-orbit coupling can be included. All electron basis sets can be used.
The separate program EPR/NMR ($ADFBIN/epr) program is no longer documented. See for the old documentation the ADF2010 EPR/NMR module.ESR/EPR g-tensor and A-tensor
