Resonance Line


a spectral line of the radiation from an atom at a frequency that coincides with the frequency of the light absorbed by the atom in its ground state. The term “resonance line” is usually applied to one or more of the strongest lines in the spectrum of resonance radiation.

All these complications are potential sources of frequency shifts of the resonance line. We then conclude that these shifts are below the percent level.
Finally, a calculation of the expected resonance line for the 2 [arrow right] 1 transition indicates that a measurement of the transition frequency at a precision better than a percent is possible.
The most common technique to assess magnetization damping in magnetic films is to measure the ferromagnetic resonance line width of the material.
1996a) with a broad resonance line at 130 ppm, a shoulder assignable to aryl carboxylic carbon, and some remaining signal intensity in the chemical shift region of O-alkyl and alkyl carbon.
To achieve accurate ferrite models, the ferrite's magnetic parameters are input, including the saturation magnetization, ferromagnetic resonance line width and Lande g factor.
The resonance line width includes the effects of both inhomogeneities and intrinsic damping.
The corresponding resonance line is narrow (~200 Hz for free heavy water compared with ~7 kHz of bound heavy water).
According to Tribelsky's explanation, this sphere has rather narrow resonance lines related to its polarization oscillations.
Two intense resonance lines at 120 ppm and 43 ppm could be observed (as shown in Fig.
As the size of the molecule being studied increases, the resonance lines generated by its various atomic components broaden and can begin to overlap, which makes it difficult or impossible to determine its structure.
As the expansion of the universe is carrying distant galaxies away from us, these resonance lines will appear shifted to the red by some amount from the wavelengths at which they appear at rest in the laboratory.
