Ball-and-stick geometry you can rotate and zoom, with the formula, molecular weight and SMILES beside it — the structure itself, not a picture of one.
caffeine, aspirin, water — or open one from inside another subject’s tree.
The model is live geometry: drag to turn it, scroll to close in.
Formula, molecular weight and SMILES, so the answer is checkable.
