Übersetzung für "Line broadening" in Deutsch

The alloy broadening is one of the line broadening mechanisms.

The greater mB is, the smaller is the resulting line broadening in the signal spectrum.

These read gradients produce a degradation in homogeneity of the constant magnetic field and, therewith, a systematic line-broadening.

Typical limit values for the maximum line width and broadening in the case of scattering are in the region of a few MHz.

In the Fourier spectrum, this leads to line broadening on the line of the rotation frequency and on the harmonics.

Imaging effects may therefore be tolerated quite well when they systematically contribute to line broadening.

Class influences which are still present act on resonant frequency shift and line broadening similarly to the material density alteration in the same way and are removed in the course of division in equation (3) in order to obtain the measurement signal.

For magnesium dihalide in active form it is meant a dihalide in the X-ray spectrum of which the most intense reflection line shows a broadening compared to the line of the corresponding halide in the inactive form or the line is replaced by a halo shifted with respect to the position of said line.

Furthermore, the scattered radiation must not itself contribute to any significant line broadening since, otherwise, the coherence would be destroyed.

Typical limit values for the maximum line width and broadening in the case of scattering are in the region of a few kHz or MHz.

However, if one also wants to evaluate the pressure-dependent line broadening outlined at last, it will be helpful to measure over a greater wavelength range.

Furthermore, it is known in solid-state NMR spectroscopy to rotate an NMR sample tilted at the so-called “magic angle” of approximately 54.74° in relation to the static magnetic field during the spectroscopic measurement (“MAS”=Magic Angle Spinning) in order to minimize line broadening on account of anisotropic interactions.

Further, it is known in solid-state NMR spectroscopy to rotate an NMR sample tilted at the so-called “magic angle” of approximately 54.74° in relation to the static magnetic field during the spectroscopic measurement (“MAS”=Magic Angle Spinning) in order to minimize line broadening on account of anisotropic interactions.

In solid state NMR spectroscopy, an NMR sample is usually rotated in a tilted position at the so-called “magic angle” of approximately 54.74° with respect to the static magnetic field (“MAS”=Magic Angle Spinning) during spectroscopic measurement in order to reduce line broadening due to anisotropic interactions.

In this way, line broadening due to these interactions can be significantly reduced, ideally even to the natural line width.

Severe line broadening, which can be easily handled by the method according to the invention, occurs with liquid samples, particularly in NMR.

One requirement of high-resolution NMR is to adjust the static field B 0 to be so homogeneous that spectral line broadening is smaller than the natural line widths due to inhomogeneities.

This is done in that, if necessary after demodulation or down-mixing of the signal with a carrier frequency, for example at the mains frequency and/or its integer harmonics divided by the number of pole pairs, a Fourier transform is produced in sections, and the resulting spectrum is analyzed for line broadening and/or sidebands and/or for frequency lines in baseband.

In this case, possibly after demodulation or down-mixing of the signal, sections are preferably subjected to a Fourier transformation at a carrier frequency, in particular at the system frequency or harmonics thereof, and the resulting spectrum is analyzed for instances of line broadening of the harmonics, in the case of frequency modulations, or for sidebands, or else bands in the baseband, in the case of amplitude modulations.

One problem of high-resolution NMR is that a temperature gradient in the test samples produces artifacts in the spectra (line broadening etc.).

It cannot be seen from an X-ray diffractogram, due to line broadening, whether it is apatite or other structures.

Different dehydration states in a sample therefore result in line broadening because many peaks are slightly shifted relative to one another, which, disadvantageously, provides less spectral information.

Correspondingly, the occurrence of oscillations can be recognized visually or automatically using such instances of line broadening, and, in particular, their occurrence can be analyzed in temporal sequence.

He has recently published a series of papers on the polarization of the CMB radiation and detailed analysis of the narrow line broadening induced by Compton scattering on relativistic electrons.

Paramagnetic Contamination: Paramagnetic contaminations lead to dipol-dipol-interactions, which cause line broadening and thus should be avoided.
