most ChemicalData molecule plots missing?
i'm getting a lot of missing molecule plots for even the simplest and most common molecules in ChemicalData... in:= ChemicalData["CarbonMonoxide", "MoleculePlot"] ChemicalData["NitrogenDioxide", "MoleculePlot"] out= Missing["NotAvailable"] Missing["NotAvailable"] most hydrocarbons are also missing. is this normal, or could there be something wrong with my mathematica install or a cached curated data problem? i was expecting molecule plots to be automatically generated from the chemical formulas, but looks like it's not. i guess its down to manually using graphics3d, spheres, and cylinders ... cheers, Mitch
