This makes it highly probable that a nearby molecule will emit into the mode of the waveguide.
It operates by sending mechanical vibrations to nearby molecules and then analyses the resulting echoes.
The win is this: once it feels the forces associated with other nearby molecules, the color of light it will absorb changes.
When the two molecules interact, their structure, as well as that of nearby molecules of the solution containing them, is changed.
However, if the nearby molecules reorient and move around fast enough, the vibration will essentially occur at an averaged frequency, and therefore have a smaller linewidth.
You need nearby molecules attempting to come out of solution at the same time to find each other and bond.
These come about when a nonpolar molecule becomes temporarily polarized due to interactions with a nearby polar molecule.
The device also creates a field in which nearby molecules are also destroyed, and each dissolved molecule widens the reach of the field.
In addition, statistical ensembles in physics are often built on a principle of locality: that all interactions are only between neighboring atoms or nearby molecules.
This small charge will induce a corresponding dipole in a nearby molecule; causing an attraction between the two.
