“…The zfs for 2 , determined here by two independent methods, is significantly larger than that reported for mononuclear V II complexes, with the closest being vanadocene, for which the zfs was indirectly determined by X‐ and Q‐band EPR to be | D |=2.3 cm −1 1f. The zfs of V(II) has been reported for a number of systems in which the ion is coordinated in homoleptic, six‐coordinate environments with N,12a O,12b or halide12c donors. In these highly symmetric cases, | D | <0.2 cm −1 , and is often <0.01 cm −1 , which allowed its facile measurement by X‐band EPR.…”

Ein Arenring maskiert den niedervalenten und niederkoordinierten VII‐Komplex [(nacnac)V(Ntol2)] und ermöglicht so die einfache Koordination terminaler Liganden an das Vanadiumzentrum. Die Aktivierung kleiner Moleküle durch diesen S=3/2‐Komplex bietet einen einfachen Zugang zu einer breiten Auswahl von Ligandengerüsten, wie terminalen VIV‐Imido‐, VIV‐Cyclopropen‐ und VV‐Nitrid‐Komplexen sowie dem ersten VV‐cyclo‐P3‐Komplex (siehe Schema).

“…However, the inter-Kramers transitions cannot be observed in such conditions, and thus conventional EPR is not informative with regard to the zfs if the latter significantly exceeds the microwave quantum energy. Figures 6a and 6b here, side by side [133], and similarly in simple halides (LiCl, NaCl, etc. ), wherein the zfs is even smaller: D  0.06(2) cm -1 [134].…”

In this Review, we discuss the advantages of performing electron paramagnetic resonance (EPR) on coordination and metalloorganic complexes containing various oxidation states of vanadium, from +4 to +2, using the high-frequency and-field version of this technique, known as HFEPR. Thus, HFEPR is advantageous in investigating (S = 1/2) V(IV) species due to its higher g-factor resolution over conventional EPR, albeit at the price of losing the hyperfine structure resolution due to g-strain. It is very much desirable in characterizing (S = 3/2) V(II) complexes since it is capable of precisely and accurately measuring the zero-field splitting present in these species. Finally, HFEPR is indispensable in investigating (S = 1) V(III) species, which in conventional conditions are often "EPR-silent" due to the combination of their large zero-field splitting and integer spin number. The use of HFEPR thus can provide additional information regarding the oxidation state of the metal and the coordination geometry.

Strong coupling between whispering gallery modes and chromium ions in ruby

et al. 2014

We report the study of interactions between cavity photons and paramagnetic Cr 3+ spins in a ruby (Cr 3+ :Al2O3) Whispering Gallery mode (WGM) resonator. Examining the system at microwave frequencies and millikelvin temperatures, spin-photon couplings up to 610 MHz or about 5% of photon energy are observed between the impurity spins and high quality factor (Q > 10 5 ) WGM. Large tunability and spin-spin interaction allows operation in the strong coupling regime. The system exhibits behaviour not predicted by the usual Tavis-Cummings model because of interactions within the two-level spin bath, and the existence of numerous photonic modes.
