Abstract
We report the results of a study of the properties of the paramagnetic triplet state of eosin Y and erythrosin. This information is a prereq uisite for their use as EPR probes. The magnetic anisotropy in both mo lecules is found to be suitable for monitoring slow rotational dynamic s, Interestingly, the magnetic interactions in eosin show a large anis otropy in the x-y plane (E is roughly equal to D/3) of the Magnetic fr ame. Erythrosin on the other hand, has a virtually isotropic interacti on in that plane (E small compared to D/3).
