_chemical.enantioexcess_bulk
Name:_chemical.enantioexcess_bulk
Alias:
_chemical_enantioexcess_bulk
Definition:
The enantioexcess of the bulk material from which the crystals
were grown. A value of 0.0 indicates the racemate. A value of
1.0 indicates that the compound is enantiomerically pure.
Enantioexcess is defined in the IUPAC Recommendations
(Moss et al., 1996). The composition of the crystal
and bulk must be the same.
