Sentences with phrase «vibrational motion»
"Vibrational motion" refers to the back-and-forth or up-and-down movement of something, usually very fast. It can be like when a guitar string moves quickly to create sound or when a phone vibrates to notify you of a message. Full definition
When a light wave with that same natural frequency impinges upon an atom, then the electrons of that atom will be set into vibrational motion.

To the extent that molecular vibrational motion is harmonic, this is an absolute rule.
«After we have shaken the condensate with the pulse, it performs (exhibits) two different vibrational motions at the same time,» says van Frank.
Almost by definition an oxymoron because of the relationship between vibrational motions and IR absorptions.
Finally, heat content of the CO2 will be higher because of the higher specific heat at constant volume because there are 3 modes of vibrational motion rather than one (N2).
«In contrast, low - energy electrons interact with the whole molecular network, which includes the chemical bonds and vibrational motion of the atoms within the substance, and their scattering is currently too complex to predict with a model.
However, molecular vibrational motion (loosely defined as the relative motion of the atoms in a molecule relative to each other) is not quite harmonic (shown by the solid line), and the vibrational selection rule is not absolute in transitions between distant vibrational levels.
Nevertheless, the vibrational motions act back on the electrons, modulate their spatial distribution and change the electric and optical properties of the crystal on a time scale which is shorter than 1 ps (10 - 12 s).
When atoms absorb light of a specific wavelength, they undergo changes in their vibrational motions that are specific to that element's molecular structure and chemical bonds.
``... this pulls the carbon in one direction and the oxygens in another, so an electromagnetic wave that vibrates at the correct frequency can excite the molecule into a vibrational motion in which the carbon atom moves in the opposite direction to the two oxygen atoms.
