The principles of soil spectroscopy are based in nuclear physics. Elements in the soil react in unique ways to the energy from the electromagnetic spectrum, reflecting some wavelengths and absorbing others. The reflected wavelengths give scientists clues to which minerals and elements are present and in what quantities. That information can then be related to certain soil properties, like whether it's suitable for certain crops, or whether it's effectively sequestering carbon. 2, record 1, English, - soil%20spectroscopy

Stationary nuclear Overhauser effect. NMR [nuclear magnetic resonance] spectroscopy based on the nuclear Overhauser effect(NOE) between dipolar coupled nuclei is one of the most commonly used techniques to determine the spatial structure of proteins. Generally speaking the NOE describes the transfer of spin polarization from one spin population to another. The magnitude of the NOE highly depends on the distance between the dipolar coupled spins such that it can be used to determine interatomar distances within molecules. 1, record 4, English, - %20stationary%20nuclear%20Overhauser%20effect

Elle présente l’avantage de ne pas nécessiter l’utilisation de sources radioactives de photons [gamma] incidents, qui peuvent être difficiles à fabriquer, de durée de vie qui peut être courte et d’intensité évidemment limitée.

The magic angle is a root of a second-order Legendre polynomial,... and so any interaction which depends on this second-order Legendre polynomial vanishes at the magic angle.

Contrairement à d’autres méthodes spectroscopiques, la RMN [résonance magnétique nucléaire] possède la particularité de sonder l’environnement local d’un noyau choisi à travers la caractérisation des interactions influençant la relaxation. [...] La RMN des solides n’en est pas encore à ce niveau de haute résolution, sauf en technique HRMAS [expériences haute résolution à l'angle magique] pour les échantillons dits «mous» comme les résines gels, plantes […] En effet la rigidité du réseau cristallin accentue fortement l’influence sur la relaxation d’interactions d’origines diverses. De plus les études se font principalement sur des échantillons de poudre puisqu’il est difficile d’obtenir des monocristaux de taille suffisante (>1 mm³). Ainsi le caractère anisotrope des interactions et la présence de cristalittes aux orientations multiples génèrent des élargissements de raies de résonance. La technique la plus souvent utilisée pour éliminer, ou tout au moins réduire ces élargissements consiste à mettre l’échantillon en rotation à l’angle magique (angle de 54,7° par rapport au champ magnétique statique). 2, record 6, French, - angle%20magique

Exchange(intermediate, fast, slow, chemical and conformational) : Exchange is a kinetic process between two(or more) states that is characterized by a rate constant. In NMR [nuclear magnetic resonance] spectroscopy, exchange is classified into fast, intermediate and slow depending on the size of the rate constant with respect to chemical shift(which is measured in the same units(Hz) as the rate constant). In the fast exchange regime, the rate is much larger than the difference in chemical shift between the two states and the NMR signal will be at the weighted average position of the two states. In slow exchange, signals for both states are observable and the intensities are proportional to the populations of the two states. In intermediate exchange, the transition between the signals seen for slow and fast exchange takes place, resulting in very broad and often non-observable signals. 1, record 7, English, - fast%20exchange

The crystal thickness is selected on the basis of the gamma-ray energy region relevant to the application of interest, with the small thicknesses optimum for low-energy measurements(for example in the L-x-ray region for special nuclear material).

La technique actuelle basée sur l’utilisation d’implanteurs (accélérateurs d’ions de faible énergie), permet de réaliser des jonctions abruptes et minces grâce à un contrôle très précis de la position en profondeur des dopants (B pour type P et As pour type N) à l’intérieur d’un substrat de Si (réduction de la zone morte du dispositif) de haute résistivité (de type N–).

[Nuclear radiation detector. ] Pile-Up Rejection. If two pulses arrive within the so-called measurement time(peaking time) the output pulse will have a distorted amplitude. The pile-up rejector circuit is used to prevent the measurement of these distorted pulses. The pile-up rejector is implemented by adding a fast pulse-shaping amplifier with a very short shaping time constant in parallel with the slow spectroscopy amplifier. 1, record 12, English, - pile%2Dup%20rejector%20circuit

[Détecteur de rayonnements nucléaires.] Circuit anti-empilement […] : si le temps séparant deux événements est plus court que la durée du signal en sortie d’amplificateur, ces deux signaux vont s’empiler. Pour réduire ce phénomène, on peut diminuer les constantes de temps mais on élargit la bande passante et on diminue le rapport signal/bruit. Par ailleurs avec des constantes de temps qui ne seraient plus assez grandes devant le temps de montée du signal issu du pré-amplificateur, le défaut balistique n’est plus constant. Le rôle du circuit anti-empilement est de rejeter le signal si un deuxième événement survient dans un temps inférieur à la durée de l’impulsion. 1, record 12, French, - circuit%20anti%2Dempilement

This course is designed for chemistry students wishing to become familiar with the use of high resolution nuclear magnetic resonance(NMR) spectroscopy and mass spectrometry for the determination of molecular structure and dynamics in solution. The NMR part of the course deals with analysis of second-order proton spectra, with extraction of coupling constants and chemical shifts from spectra. Then the topics of pulsed and Fourier transform NMR are introduced and applied to natural abundance 13C spectra. Problem solving with combined 1H and 13C NMR data is emphasized. Subsequently the use of spin lattice relaxation times for dynamics is discussed, followed by an introduction to 2 dimensional(2D) NMR. 1, record 18, English, - 2%20dimensional%20NMR
