The printed Fock matrix in natural orbital basis has only 4 decimal digits and the smallest non-zero matrix element is already 0.0001 Hatree (~21.9 cm-1), which is too large in some cases. Is there any way to get high precision natural orbital Fock matrixes in the built-in NBO 3.1? I do not have access to newer NBO versions. Thanks and best wishes, Xing
