A central objective of chemical and molecular physics is to understand molecules as quantum mechanical systems. The complex internal dynamics of such systems evolve across wide energy and time scales, exhibited by a variety ...
For the past 30 years, the significance of the anomalously low ortho-to-para ratios (OPRs) of gaseous water (H2O) in interstellar space has remained unknown. (In ortho hydrogen molecules, both nuclei spin in the same direction, ...
Small spheres suspended in a liquid move enough like molecules that the physics for one can be used to mimic the physics of the other.
