摘要：

Solid-state transitions in crystalline tetracene have been investigated by Raman spectroscopy and by anisotropy of the effect of a magnetic field on its prompt fluorescence. Discontinuous changes in the temperature dependence of Raman lattice modes and new phonon lines occur near 182 and 144 K, signifying the occurrence of two phase transitions. The magnetic anisotropy effect shows a gradual change with temperature, suggesting the transition at 182 K is preceded by a continuous rotation of the intermolecular plane. © 1979.
