IC parameters in topology files.

In various places in the topology files I found lines like

IC   CG  CD1  CE1  CZ   0.0000  0.00  0.00 0.0000

I can find however no referenc to this IC parameter in the manual. Is 
this the same as the IMPROPER ?

Has anyone already done a calculation on a heme group containing protein. 
If so, can you give me an idea about the force constants you used for the 
Cys-Heme and ligand-heme bonds ?
