Greetings! I am trying to run some ab-initio calculations on europium organometallic complexes through Hyperchem. I cannot seem to find a suitable basis set, since none of the standard sets support Europium, and the one set that I could find at http://www.emsl.pnl.gov:2080/forms/basisform.html (WTBS) that has said element, supports Hyperchem, and has no ECPs does not support hydrogen. Any suggestions? Thanks, T. Thoms
