β¦ Synopsis
A Carr-Purcell multiple spin-echo, as modified by Meiboom and Gill, is desnibed for the 3598 MHz zero-field transition of phosphorescent quinoline CgND7 in a durene host. The results show that the dephaing of the electron spins through spectral diffusion may be lxgcly eliminated by the multiple echo technique.

We have observed a temperature dependence of the direction of the principal axes of the zero-field splitting for the triplet state of naphthalene in durene. The effect is caused by thermal excitation to a nearby local phonon state, where the spin itYes are rotated with respect to those in the lowest
## Rcceivcd 21 Jl?ly 1975 We present a theoretical model for describing spin coherence in photoexcited triplet states in zero-field under the influence of vibronic relaxation. From a comparison with experimental results in parabenzoquinone we obtain information about the properties of the excited
The kinetic parameters of the photo-excited triplet state of pentacene in p-terphenyl crystals have been calculated from the electron spin echo (ESE) decay curves in the temperature range of 5-300 K. The results suggest the calculated decay parameters depend strongly on guest deuteration, especially
