Tautomerism vs. Resonance

Tautomerismnoun

(organic chemistry) A form of isomerism in which a dynamic equilibrium between multiple isomers exists, such as that between an enol and a ketone.

Tautomerismnoun

The condition, quality, or relation of metameric substances, or their respective derivatives, which are more or less interchangeable, according as one form or the other is the more stable. It is a special case of metamerism; thus, the lactam and the lactim compounds exhibit tautomerism.

Resonancenoun

The quality of being resonant.

Resonancenoun

A resonant sound, echo, or reverberation, such as that produced by blowing over the top of a bottle.

Resonancenoun

(medicine) The sound produced by a hollow body part such as the chest cavity upon auscultation, especially that produced while the patient is speaking.

Resonancenoun

(figuratively) Something that evokes an association, or a strong emotion.

Resonancenoun

(physics) The increase in the amplitude of an oscillation of a system under the influence of a periodic force whose frequency is close to that of the system's natural frequency.

Resonancenoun

(nuclear physics) A short-lived subatomic particle or state of atomic excitation that results from the collision of atomic particles.

Resonancenoun

An increase in the strength or duration of a musical tone produced by sympathetic vibration.

Resonancenoun

(chemistry) The property of a compound that can be visualized as having two structures differing only in the distribution of electrons; mesomerism.

Resonancenoun

(astronomy) A influence of the gravitational forces of one orbiting object on the orbit of another, causing periodic perturbations.

Resonancenoun

(electronics) The condition where the inductive and capacitive reactances have equal magnitude.

Resonancenoun

The act of resounding; the quality or state of being resonant.

Resonancenoun

A prolongation or increase of any sound, either by reflection, as in a cavern or apartment the walls of which are not distant enough to return a distinct echo, or by the production of vibrations in other bodies, as a sounding-board, or the bodies of musical instruments.

Resonancenoun

A phenomenon in which a vibration or other cyclic process (such as tide cycles) of large amplitude is produced by smaller impulses, when the frequency of the external impulses is close to that of the natural cycling frequency of the process in that system.

Resonancenoun

An electric phenomenon corresponding to that of acoustic resonance, due to the existance of certain relations of the capacity, inductance, resistance, and frequency of an alternating circuit; the tuning of a radio transmitter or receiver to send or detect waves of specific frequencies depends on this phenomenon.

Resonancenoun

an excited state of a stable particle causing a sharp maximum in the probability of absorption of electromagnetic radiation

Resonancenoun

a vibration of large amplitude produced by a relatively small vibration near the same frequency of vibration as the natural frequency of the resonating system

Resonancenoun

having the character of a loud deep sound; the quality of being resonant

Resonancenoun

relation of mutual understanding or trust and agreement between people

Resonancenoun

the quality imparted to voiced speech sounds by the action of the resonating chambers of the throat and mouth and nasal cavities

Resonance

Resonance describes the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts. When an oscillating force is applied at a resonant frequency of a dynamic system, the system will oscillate at a higher amplitude than when the same force is applied at other, non-resonant frequencies.Frequencies at which the response amplitude is a relative maximum are also known as resonant frequencies or resonance frequencies of the system.
