When multiple women have their periods synced at the same time. The PMS resulting from this can often be deadly for nearby males. This phenomenon is analogous to physical wave resonance.

Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique to observe local magnetic fields around atomic nuclei. The sample is placed in a magnetic field and the NMR signal is produced by excitation of the nuclei sample with radio waves into nuclear magnetic resonance, which is detected with sensitive radio receivers. The intramolecular magnetic field around an atom in a molecule changes the resonance frequency, thus giving access to details of the electronic structure of a molecule and its individual functional groups. As the fields are unique or highly characteristic to individual compounds, in modern organic chemistry practice, NMR spectroscopy is the definitive method to identify monomolecular organic compounds.
Person 1: Do you think our laboratory needs an NMR-spectrometer?
Person 2: I've heard they're unbelievably expensive, but Nuclear magnetic resonance spectroscopy (NMR) is an essential analytical procedure for sure .
