Probing the distribution of low symmetry fields by the magnetic field effect on a persistent spectral hole in the R1 line of chromium(III)-tris (2,2′-bipyridine) in glycerol

Abstract

The effect of an applied magnetic field on a spectral hole burned in the R1 line of [Cr(bpy)3]3+/glycerol is measured. The hole spreading observed deviates considerably from a behaviour expected for a trigonal system. A model taking into account a distribution of low symmetry fields provides far better agreement with experiment. The same approach was previously applied to describe the large variation of the 2E splitting in various amorphous systems. Show more
