ComputeGasteigerCharges(...)

source code 
Compute Gasteiger partial charges for molecule

 The charges are computed using an iterative procedure presented in 
 
 Ref : J.Gasteiger, M. Marseli, Iterative Equalization of Oribital Electronegatiity 
 A Rapid Access to Atomic Charges, Tetrahedron Vol 36 p3219 1980
 
 The computed charges are stored on each atom are stored a computed property ( under the name 
 _GasteigerCharge). In addition, each atom also stored the total charge for the implicit hydrogens 
 on the atom (under the property name _GasteigerHCharge)
 
 ARGUMENTS:

    - mol : the molecule of interrest
    - nIter : number of iteration (defaults to 12)
    - throwOnParamFailure : toggles whether or not an exception should be raised if parameters
      for an atom cannot be found.  If this is false (the default), all parameters for unknown
      atoms will be set to zero.  This has the effect of removing that atom from the iteration.


C++ signature:
    ComputeGasteigerCharges(RDKit::ROMol const* mol, int nIter=12, bool throwOnParamFailure=False) -> void*
