CO frequencies in Organometallics



Hi
     I am trying to compare the calculated CO vibrational frequencies
 with experimental
 frequencies in Organometallics.  But the scaling factors suggested for
 organic compounds
 in  J. Phys. Chem. 1996, 100, 16052  producing large errors.  Are there
 any special scaling
 factors for organometallic CO vibrational frequencies.  I will
 summarize.
 Thanks
 Srinivas
