The results can be interpreted in terms of anticrossings of the electron and nuclear spin sublevels of the guest molecule and cross relaxation between the electron-nuclear states of the guest and host. Such studies yield values of the zero-field splitting parameters of the triplet state and provide estimates of the nuclear hyperfine and quadrupole coupling constants of both the guest and host. A novel method for determining the magnitude of the perturbation giving rise to the level anticrossing will also be described. en_US dc.format.extent 139765 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title LEVEL ANTICROSSING AND CROSS-RELAXATION EFFECTS IN THE ODMR AND PHOSPHORESCENCE SPECTRA OF ORIENTED MOLECULAR TRIPLET STATES en_US dc.type article en_US
