Two methods for the determination of exciton structure are employed for this system (which cannot exhibit a Davydov splitting): The band-to-band (“hot band”) transition $method1$, and the heavily doped isotopic mixed crystal method. The experiments involve single crystals at low temperature $(1.5\circ K$ ) and medium high resolution ($0.5cm-1)$. Results will be discussed in terms of translationally equivalent exciton interactions and effective one-dimensional energy transfer.
