The Journal of Physical Chemistry A is a scientific journal which reports research on the chemistry of molecules - including their dynamics, spectroscopy, kinetics, structure, bonding, and quantum chemistry. It is published weekly by the American Chemical Society. Before 1997 the title was simply Journal of Physical Chemistry. Owing to the ever-growing amount of research in the area, in 1997 the journal was split into Journal of Physical Chemistry A (molecular theoretical and experimental physical chemistry) and The Journal of Physical Chemistry B (solid state, soft matter, liquids, etc.). Beginning in 2007, the latter underwent a further split, with The Journal of Physical Chemistry C now being dedicated to nanotechnology, molecular electronics, and related subjects. According to the Journal Citation Reports, the journal had an impact factor of 2.944 for 2021. Editors-in-chief 1896–1932 Wilder Dwight Bancroft, Joseph E. Trevor 1933–1951 S. C.
