OEGetAverageWeight¶
double OEGetAverageWeight(unsigned int elemno)
Returns the average atomic weight of an element, based upon the
naturally occurring abundances of its isotopes. To return the
‘monoisotopic’ weight for a particular element use the
OEGetIsotopicWeight
function like the following.
elemno = oechem.OEElemNo_O
weight = oechem.OEGetIsotopicWeight(elemno, oechem.OEGetDefaultMass(elemno))
