โฆ Synopsis
By photoselective excitation of pyrazine molecules randomly oriented in rigid glassy solvents and magnetoselective optical detection of their triplet state EPR, we have confirmed an earlier assignment of the-principal axes of the magnetic fine structure tensor.

## Abstract The structure of pyrazine partially oriented in a liquid crystal has been determined from its proton magnetic resonance spectrum utilising the ^13^C satellites (at natural abundance). Carbonโcarbon, carbonโhydrogen and hydrogenโhydrogen internuclear distance ratios have been determined.
