Hi,,, I'm a new user to Artemis and Atoms. I would like to generate a simulated EXAFS spectrum of an idealized bare 95-atom cluster of Pt (with no ligands attached to it). Looking at Cambridge data files, the largest cluster documented is 18, so I would have to make one up. I would like to arrange the 95 atoms into an idealized sphere with the standard geometry for bulk Pt-Pt bonding that can be predicted from the crystal structure (e.g. metallic radius = 139nm, metallic separation = 277.5nm separation, etc.) I understand this can be done using Artemis and Atoms. I'm relatively new to using the software (prodominantly know how to use Athena for plotting the experimental EXAFS data , not much more). Could anyone provide suggestions on how to get started on this task? E.g. Generating the crystal data and displaying the EXAFS of the resulting bare cluster? Charles
