One way is though the use of spectroscopic methods. Spectroscopy is the study of the interaction of energy with matter. When energy is applied to matter it can be absorbed, emitted, cause a chemical change, or be transmitted. Nuclear magnetic resonance (NMR) spectrometry –energy absorption by molecules that have been placed in a strong magnetic field. Mass spectrometry (MS) — molecular structure probed by bombarding molecules with a beam of high energy electrons
