Toward Applications of β-NMR Spectroscopy in Chemistry and Biochemistry

“…For a more elaborate description of the technique see, for example, Refs. [9][10][11]. The first applications of β-NMR were proposed by F. L. Shapiro in 1958 [12].…”

“…impact and applications (some of which is conducted at large scale facilities ISOLDE [3], GANIL [6], RIKEN [7], TRIUMF [13]) [3][4][5][6][7][8][9][10][11][12][13][14]. In chemistry and biochemistry the advantages of β-NMR spectroscopy are: (1) high sensitivity, since as few as 10 5 -10 7 ions are required to record the signal and (2) access to chemical elements that are otherwise difficult to interrogate spectroscopically.…”

“…In addition to this, some of the elements which are problematic in conventional NMR spectroscopy, such as Mg, Ca, Cu, and Zn, already are or might be accessible with β-NMR spectroscopy [3][4][5]. Several applications of β-NMR spectroscopy in nuclear, solid state physics, and materials science have been published over the past decades [3][4][5][6][7][8][9][10][11][12][13][14] and references therein, and with the project described herein, we aim to advance the applications to solution chemistry and biochemistry [5].…”

Solid State NMR Spectroscopy a Valuable Technique for Structural Insights of Advanced Thin Film Materials: A Review

“…A continuous RF field is applied on the sample leading to the nuclear sub-level transitions at the resonance frequency, and the decrease in spin polarization as the change in β-decay asymmetry is recorded. The employment of a highly spin-polarized radioactive beam with β-NMR creates a novel nuclear method of detection that has enough sensitivity to detect the presence of a single probe nucleus and build up a typical spectrum [150]. Due to its novel features such as high magnetic fields and the ability to control the depth of implantation ranging between 2-200 nm, β-NMR found many applications in surface science [151], insulators [152], semiconductors [153,154], antiferromagnetics [155] and thin films [73,149,[156][157][158].…”

Billion‐Fold Enhancement in Sensitivity of Nuclear Magnetic Resonance Spectroscopy for Magnesium Ions in Solution

“…As the direction of emission of the b-particles depends on the nuclear spin direction, the b-particles are emitted anisotropically. [7] In analogy to conventional NMR spectroscopy, the probe nuclei in the system of interest are placed in an external magnetic field and exposed to radio-frequency electromagnetic radiation. At the resonance frequency, transitions between magnetic sub-states occur, giving rise to a loss of nuclear spin polarization and, thus, loss of anisotropy in the b-particle emission.…”
