WebAccurate quadrupole coupling constants have been determined from the hyperfine splittings of the J K Γ=2 0 B 1 ←1 1 B 2 and 2 0 E 1 +1←1 1 E 1 — 1 transitions (Γ being a symmetry label) in the ground state of methyl amine, CH 3 NH 2, recorded with a microwave Fourier transform molecular beam spectrometer.These constants, combined with the … WebWe report measurements of the hyperfine coupling constant for the 8p 2 P 1/2 level of atomic cesium, 133 Cs, with a relative uncertainty of ∼0.019%. Our result is A = 42.933 (8) MHz, ten times more precise than the previous best measurement, and in good agreement with recent theoretical results.
The theory of hyperfine structure comes directly from electromagnetism, consisting of the interaction of the nuclear multipole moments (excluding the electric monopole) with internally generated fields. The theory is derived first for the atomic case, but can be applied to each nucleus in a molecule. … Meer weergeven In atomic physics, hyperfine structure is defined by small shifts in otherwise degenerate energy levels and the resulting splittings in those energy levels of atoms, molecules, and ions, due to electromagnetic … Meer weergeven Hyperfine interactions can be measured, among other ways, in atomic and molecular spectra and in electron paramagnetic resonance spectra of free radicals and transition-metal ions.
