Modeling the absorption spectrum of the permanganate ion in vacuum and in aqueous solution
The absorption spectrum of the MnO4 - ion has been a test-bed for quantum-chemical methods over the last decades. Its correct description requires highly-correlated multiconfigurational methods, which are incompatible with the inclusion of finite-temperature and solvent effects due to their high computational demands. Therefore, implicit solvent models are usually employed. Here we show that impli
