Vibrational Relaxation of Anharmonic Oscillators with Vibration–Vibration and Vibration–Translation Energy Exchanges

The Journal of Chemical Physics, 1970
The vibrational relaxation of a system of anharmonic oscillators with high initial vibrational energy into a low-temperature heat bath was studied. It was assumed that the vibration–vibration quasisteady population distribution was instantly established, and during the longer time scale the level population distribution was controlled by a continuous ...

Vibrational anharmonicity and multilevel vibrational dephasing from vibrational echo beats

The Journal of Chemical Physics, 1997
Vibrational echo experiments were performed on the IR active CO stretching modes (∼2000 cm−1) of rhodium dicarbonylacetylacetonate [Rh(CO)2acac] and tungsten hexacarbonyl [W(CO)6] in dibutylphthalate and a mutant of myoglobin-CO (H64V-CO) in glycerol–water using ps IR pulses from a free electron laser.

An Investigation of the Vibrations of Plates Vibrated at the Centre

Science, 1880
Most of the plates used were window panes of various shapes and sizes, they were vibrated by rubbing an attached glass rod. The tubes, which were about-ji of an inch in diameter and 20 inches long, were attached at right angles to the face of the plate with sealing wax.

Vibrator, vibration unit, and vibrator control method

The Journal of the Acoustical Society of America, 2006
A vibrator has massaging balls supported by a treating unit that may be shifted along a subject portion for treatment, guided by guiding members. The treating unit is supported by a supporting structure with respect to the guiding members. A position or orientation altering mechanism is provided for altering the position of the treatment unit in a ...

Vibration Isolation and Chaotic Vibration

Volume 5: 19th Biennial Conference on Mechanical Vibration and Noise, Parts A, B, and C, 2003
Taking single degree of freedom vibration isolation system under simple harmonic excitation as an example, and considering the energy, the vibration isolation performance in different conditions was studied theoretically and numerically. The results shows that when the simple harmonic excitation import energy is definite, the vibration isolation ...

Itch and Vibration

Science, 1965
Itch produced by application of cowage to the wrist was reduced in intensity by vibration of the stimulated area. Application of vibration to the opposite wrist also reduced intensity. The results may be attributed to physiological activities occurring at the early stages of information transmission.
