For example, molecular rotation and therefore reactivity depends on the presence of a solvent, electronic angular momentum in solids is coupled to lattice phonons, highly excited atomic levels can be perturbed by a surrounding ultracold gas.
Mechanistic studies investigate enhanced emission through restriction of molecular rotation, crystallization, and fluorescence spectroscopy.
Having the lowest carbon chain length in the series, the mobility of molecular rotation in 3OBA has led to increase in flow of current in anisotropic LCs matrix compared to that in other compounds upon their gradual increased chain lengths in the series.
It should be pointed out that this constant is not compatible with conventional theory of molecular rotation (i.e.
This includes the region that will affect molecular rotation, though the preferred frequency of 2,450 MHz chosen by some microwave instrumentation manufacturers falls below any of the rotational transitions that will occur in molecules.
