Visualizing optical excitations in a pentacene crystal reveals a delocalized exciton wavefunction with charge transfer character.
As prototypical organic systems, pentacene and PTCDA are central to the growing field of molecular-scale science, yet their electronic and optical properties are not well understood. Applying the tools of many-body perturbation theory to these systems, we study charge transport and optical absorption, and reveal the nature of optically generated excitons.
