 Summary --- Polarization functions for transition metals
 My sincere thanks to the following for their replies:
 J. Lohrenz 	(lohrenz - at - oci.unizh.ch)
 S. Dapprich     (dapprich - at - Mailer.Uni-Marburg.DE)
 A. Ehlers       (ehlers - at - iodine.chem.vu.nl)
 P.-O. Norrby    (peon - at - medchem.dfh.dk)
 All point to the following paper:
 A. W. Ehlers, M. Boehme, S. Dapprich, A. Gobbi, A. Hoellwarth, V. Jonas, K.
 F. Koehler, R. Stegmann, A. Veldkamp and G. Frenking, Chem. Phys. Lett.
 1993, 208, 111.
 The values for Fe, Co, Ni are 2.462, 2.780 and 3.130 resp.
 The reply from Dr. P.-O. Norrby has additional information and his message
 is included here in its entirety:
         There are, but of course only for use with specific basis sets.
 Frenking et al. have optimized the simplest possible type of f-functions
 (just 1 gaussian) for use with one of Hay & Wadt's ECP:s, I believe you
 could use them with, for example, LANL2DZ.  The reference is "Ehlers et
 al., Chem.Phys.Lett. 208 (1993) 111", the single gaussian exponents for Fe,
 Co, and Ni are 2.462, 2.780, and 3.130, respectively.
         I have, by personal communication, got more extensive polarizations
 for other TM's, you could try to make a literature search for Margareta
 Blomberg and Per Siegbahn, that should give you some pointers.
