Dear Ana, maybe I am a little bit picky here, but actually you cannot convert U(ij) into U(iso), because U(ij) result from a fit with anisotropic displacement parameters, while U(iso) results from a fit with isotropic displacement parameters. Thus, to convert one into the other means repeating th

Dear Ana, I know that the Gretep program (Grenoble Thermal Ellipsoids Plot Program)can make this conversion. Best regards, Mario Macías Univeersidad Industrial de Santander Colombia Dear All, > > > > How can I convert the “anisotropic temperature factors” (uij) into an > “isotropic temperatu

Dear All, How can I convert the “anisotropic temperature factors” (uij) into an “isotropic temperature factor” (Uiso)? Thank you! ana Dr. Ana Isabel Becerro Instituto de Ciencia de Materiales de Sevilla - Dpto. Química Inorgánica (CSIC-US) C/ Américo Vespucio, 49 41092 Se
