The transition between the quanta of lattice mode " i " vibrational energy ( \ hbar \ Omega _ i ).
22.
In comparison to the photon case when the electromagnetic field is quantised, the quantum of vibrational energy is called a phonon.
23.
Ultrasonic welding of thermoplastics causes local melting of the plastic due to absorption of vibrational energy along the joint to be welded.
24.
What this means is that when material bodies vibrate, they create a vibrational energy that travels in pressure waves through a medium.
25.
Each vibrational degree of freedom confers TWO total degrees of freedom, since vibrational energy mode partitions into 1 kinetic and 1 potential mode.
26.
However, the amount of vibrational energy that a molecule has continually changes due to collisions and other interactions with other molecules in the sample.
27.
It has been claimed that human olfactory receptors are capable of distinguishing between deuterated and undeuterated isotopomers of cyclopentadecanone by vibrational energy level sensing.
28.
Collisions with other molecules cause the excited molecule to lose vibrational energy until it reaches the lowest vibrational state of the excited electronic state.
29.
The reflex decreases the transmission of vibrational energy to the cochlea, where it is converted into electrical impulses to be processed by the brain.
30.
In the BEC s, the P-R modes have the same energy, which explains the zero point vibrational energies of helium in preventing lattice formation.
