Dear Turbomole Developers,
May I suggest to print in ricc2 (at the end of CCSD) the largest double-substitution amplitude as yet another diagnostic of multireference character ? To make it clear, I mean the following quantity:
max|t2| := maxij,ab|tijab|.
Surely, I am aware that max |t2| is not orbital-rotation invariant and that the D2 diagnostic is possibly better founded from a theoretical standpoint. Nonetheless, for making comparisons with the literature, it would be very convenient to have max |t2| as well. I guess, this diagnostic would be also pretty straightforward to implement.
