_chemical_enantioexcess_bulk_technique

Name:
'_chemical_enantioexcess_bulk_technique'

Definition:

   The experimental technique used to determine the
   enantioexcess of the bulk compound.

The data value must be one of the following:

`OA`	Enantioexcess determined by measurement of the specific rotation of the optical activity of the bulk compound in solution.

`CD`	Enantioexcess determined by measurement of the visible/near UV circular dichroism spectrum of the bulk compound in solution.

`EC`	Enantioexcess determined by enantioselective chromatography of the bulk compound in solution.

other Enantioexcess determined by a technique not included elsewhere in this list.
