MRCC_METHOD

If more than one root is requested and calc=1, LR-CC (EOM-CC) calculation is performed automatically for the excited states. This overrides all automatic determination of method and will only work with energy(). This becomes CC/CI (option #5) in fort.56 | begin{tabular}{ccc} | Value & Method & Description \ | hline | 1 & CC & \ | 2 & CC(n-1)[n] & \ | 3 & CC(n-1)(n) & (CC(n-1)[n] energy is also calculated) \ | 4 & CC(n-1)(n)_L & (CC(n-1)[n] and CC(n-1)(n) energies are also calculated) \ | 5 & CC(n)-1a & \ | 6 & CC(n)-1b & \ | 7 & CCn & \ | 8 & CC(n)-3 & \ | end{tabular}
