anharmonicity उदाहरण वाक्य

Anharmonicity plays a role in lattice and molecular vibrations, in quantum oscillations ( see ), and in acoustics.
Anharmonicity also modifies the energy profile of the resonance curve, leading to interesting phenomena such as the foldover effect and superharmonic resonance.
An example of the effects of anharmonicity is the thermal expansion of solids, which is usually studied within the quasi-harmonic approximation.
These three terms alone give rise to the Jaynes-Cummings ladder of dressed states, and the associated anharmonicity in the energy spectrum.
In reality, this expression has to be modified for the effects of anharmonicity of the vibrations, for centrifugal distortion and for Coriolis coupling.

In infrared spectroscopy he studied molecular vibrations as well as overtone bands in hydrogen-bonded systems, and the effect of hydrogen bonds on vibrational anharmonicity.
I might also say that if you want to get scientificky, our pages Harmonic oscillator, resonance, harmonic, and anharmonicity might be of interest.
Studying vibrating anharmonic systems using quantum mechanics is a computationally demanding task because anharmonicity not only makes the potential experienced by each oscillator more complicated, but also introduces coupling between the oscillators.
This is because, although the model does account for bond stretching due to rotation, it ignores any bond stretching due to vibrational energy in the bond ( anharmonicity in the potential ).
Because it is a statistical sampling method, PIMC takes into account all the anharmonicity, and because it is quantum, it takes into account all quantum effects ( with the exception of the exchange interaction usually ).
