In high resolution ESR spectroscopy of e.g. Moreover, we also utilized the phase-modulated OODR spectra to measure the HFS of the Cs 7S 1/2 state [14]. The constructed operator cannot contribute to hyperfine splittings in the A-species manifold because its matrix elements within the set … Detection in the resonance radiation of a Na ‐atomic beam excited by a frequency‐variable dye laser. Zero Field Splitting (ZFS) vs. Zeeman Splitting Kramer’s Doublets Kramer’s Doublets: Effective half-integer spin states (S = 5/2, 3/2, 1/2, etc.) As one can see from (17) and fig.

The purely dipolar part is expressed by the second, traceless matrix. Previously, fine and hyperfine structure measure­ ments of molecular Rydberg states by Dopper-free tech­ niques have been limited to a few states of Hz and Dz. information: g-values and hyperfine couplings, though spin-relaxation information can also be important to more advanced practitioners. As hyperfine structure splits fine structure into smaller components, superhyperfine structure further splits hyperfine structure. splitting These energy shifts are only about ten-millionths of an electron volt—really very small compared with $10$ electron volts!
