Spectroscopy, quantum chemistry and molecular physics
APR 01, 1968
Where does the boundary between physics and chemistry lie? The development of molecular‐structure models shows how ideas have passed freely between the two disciplines, with electromagnetic spectroscopy acting as the background continuum.
CERTAIN AREAS OF RESEARCH that used to be actively pursued by people called physicists in physics laboratories have now to a large extent, although not entirely, migrated to chemistry laboratories. Among the most prominent of the areas that have moved from physics toward chemistry are molecular spectroscopy, the theory of molecular structure and spectra and certain related areas, for example molecular mass spectroscopy. All these various areas are usually called “molecular physics” if carried on in physics departments or “chemical physics” if in chemistry departments.

With strong magnetic fields and intense lasers or pulsed electric currents, physicists can reconstruct the conditions inside astrophysical objects and create nuclear-fusion reactors.
A crude device for quantification shows how diverse aspects of distantly related organisms reflect the interplay of the same underlying physical factors.
