When organic chemists submit a paper detailing the synthesis of a new molecule to the likes of the Journal of Organic Chemistry, they must comply with a set of well-established requirements.

The researchers have to include nuclear magnetic resonance and infrared spectra, submit mass spectrometry data, and report melting points at each stage of the molecule-making process. Yield needs to be calculated, and for chiral compounds, optical rotation measured.

Chemists use this battery of analytical . . .
