Measurement and Analysis of Vibronic Coupling in Two Dysprosium(III) Complexes of Opposite Magnetic Anisotropy.

ABSTRACT: The loss of magnetic memory in single-molecule magnets (SMMs) is caused by the coupling of molecular vibrations to spin states, which plays a significant role in magnetic relaxation processes. Gaining direct evidence of vibronic coupling using experimental techniques is critical to understanding and controlling this phenomenon. Most studies focus on assessing the spin-phonon coupling in SMMs to help control this relaxation; herein we gain insight by comparing the SMM [Dy(OPCy₃)₂(H₂O)₅][CF₃SO₃]₃.2(OPCy₃) to the non-SMM [Dy{N(SiMe₃)₂}₃] through collection of far-infrared magnetospectroscopy (FIRMS) spectra and validation with ab initio calculations.
