Shouldn't the NMR solvent be a chemical substance instead of molecular entity? #68
Description
Currently, we define nmrCV:NMR solvent as a molecular entity that has the role CHEBI:NMR solvent.
Working on the MIChIs I was wondering, if a NMR solvent is in fact allways a chemical substance composed of the molecular entity with the ChEBI NMR solvent role. My reasoning follows the assumption that we never use just a single molecule as the solvent but allways a portion of matter composed (ideally purely) of a certain molecule with the NMR solvent role defined in ChEBI.
If my assumption is verified as correct, we need to define NRM solvent like this:
new textual definition: A chemical substance that is used as a solvent in nuclear magnetic resonance (NMR) spectroscopy because it is composed of a molecular entity that can bear the NMR solvent role.
new logical definition: 'chemical substance' and ('has part' some ('molecular entity' and 'has role' some 'NMR solvent'))
