Title:ANOMALOUS ZEEMAN SPLITTING IN THE ROVIBRATIONAL SPECTRUM OF THE OH RADICAL SOLVATED IN SUPERFLUID HELIUM or: HOW I LEARNED TO STOP WORRYING AND LOVE THE PROVERBIAL DROPLET EFFECTS
Author(s):Douberly, Gary E.
Subject(s):Fundamental interest
Abstract:The hydroxyl radical was doped into a helium droplet, and a laser/droplet interaction zone was subjected to a homogeneous 0.425(2) Tesla magnetic field. Mid-infrared Zeeman spectroscopy reveals splittings of the \textit{Q}(3/2) $\Lambda$-doublet transitions that are 21 \% larger than those predicted by both degenerate perturbation theory and a variational treatment of the Zeeman effect. This implies simply that the product $g_{e}B\Omega_{eff}$ is 21 \% larger in superfluid helium than in the gas-phase. Although speculative, it is interesting to consider the results in the context of the Einstein-de Haas effect, in which coupling to droplet phonons induces a renormalization of the electron $g$ factor.\footnote{J.H.
