There is a simple routine in CP that estimates the amount of "spin contamination": CPV/src/spinsq.f90. Hope this helps (but I am not sure it will!) Paolo On Sun, Jul 26, 2020 at 8:36 AM Christoph Wolf wrote: > Dear all, > > I am navigating in circles here, I hope someone can "kick" me in the

Dear all, I am navigating in circles here, I hope someone can "kick" me in the right direction ;) When estimating the "spin-contamination" literature (e.g. JP Malrieu, Chem Rev 2014, 114, 429 ff) mentions that the degree of contamination is estimated by the deviation of and from their ideal
