 dear all,
 i'm looking for suitable parameters for the mm3 force field
 to model organophosphourus(iii) ligands, expecially phosphites
 (f.i. trimethyl -> P(OMe)3, triphenyl -> P(OPh)3), but
 also phosphines (f.i. trimethyl -> PMe3; triphenyl -> PPh3).
 Although the latter should be included in the standard
 parametrization, no suitable set of parameters describing the phosphites
 are found. I my resarch the TINKER package was used.
 Is there anybody out there who can give me some pointers to the needed
 parameters or even better, who has made her/his own set of parameters
 by hand.
 best regards
 Thomas
