It is shown that abrupt discontinuitlrs occur in the zero-field sphtting parameters of the lsolatcd amino acid, tryptophan, and its derivatives as a function of the wavelength of the optically detected emission from the excited triplet state. These discontmuxties Jre nttrlbuted to the convolution of

The temperature dependence of the EFR spectrum of triplet excitons in ~thracen~-teiracy~obe~ene cr$%tals reveals 3. fast relaxation between two triplet states separated by 589 + 54 cm -I. The zero-field splitting parameter D is 30% smaller in the upper state, but E remains unchanged. The lifetime of
Zero-field-splitting parameters D and E for the fullerene GO in its Jahn-Teller distorted triplet state were calculated and compared to recent experimental results. The E value vanishes due to symmetry, while we obtained a non-zero k) value of D = -0.009 cm-' in the Ds distorted lowest triplet state
Zero-field splitting parameters of L-fluoro-and 24luoronaphthalene in single crystal hosts of durene and biphenyl have heen measured in experiments near zero magnetic field. Disagreements with previous reports concerning the effect of fluorine on the ZFS Parameters are discussed and are shown to ari
