Hi CCLers,
 I am going to model some Se-methyl Methanephosphonoselenoate derivatives
 and I am looking specifically for the following Molecular Mechanics
 parameters:
 Stretching :
 Se ? C
 Se ? P
 Bending:
 C ? Se ? P
 Se ? P = O
 Se ? P ? O
 Se ? P ? C
 Torsional:
 C ? Se ? P = O
 C ? Se ? P ? C
 C ? Se ? P ? O
 Se ? P ? O ? C
 Any experimental or theoretical reference is appreciated. I  will
 summarize the replies for the list. Thanks very much in advance.
