Vibrational anharmonicity and multilevel vibrational dephasing from vibrational echo beats
The Journal of Chemical Physics, 1997Vibrational 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, 1880Most 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, 2006A 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, 2003Taking 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 ...

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.

Vibration and Vibration Control
1990Vibration in machinery and structures is caused by the disturbing forces from, for example, reciprocating masses, unbalanced rotating masses, variable fluid pressure in hydraulic systems, turbulent wind loadings, wave action on structures, ground effects on vehicles, etc.

Clinical Biomechanics, 1986
This note introduces the reader to the general background of human responses to vibration. It covers some simple theory, the practical problems of measurement and the biodynamic responses to vibration. It touches on the possibility of vibration leading to low back disorders, available standards and vibration of the extremities.

Vibrational spectroscopy— degenerate vibrations
2001This chapter discusses the role of symmetry in infrared and Raman vibrational spectroscopy. It examines the relationship between vibrational symmetry and spectroscopic methods of characterization, which is considered one of the main purposes behind identifying the symmetries of different molecular vibrations.
