Abstract
The magnetic properties of the self-trapped excited triplet state in the Biphenyl-Tetracyanobenzene (1:1) crystal at low temperature (1.25 - 4.2 K) by means of zero-field optical detection of magnetic resonance (ODMR) monitoring phosphorescence have been investigated. The structure of the zero-field transitions has been interpreted as due to the whole set of transitions that occurs at zero-field in the levels manifold of the B-TCNB excited triplet state. Simulations of the ODMR lineshape has provided information on the quadrupole tensor components of TCNB.
