+ with specific emphasis on spectroscopic properties of open-shell molecules.
+  It features a wide variety of standard quantum chemical methods ranging from semiempirical methods to DFT to single-
+ and multireference correlated ab initio methods.
+ It can also treat environmental and relativistic effects."""
