AbstractTemperature modulation spectroscopy is used to obtain the temperature dependences of oscillator strength, exciton transition energy, and linewidth for a copper phthalocyanine thin film. With increasing temperature, the oscillator strength exhibits a pronounced decrease for charge transfer (CT) excitons, making this technique suitable for differentiating exciton types. From the measured magnitude and temperature dependence of the CT oscillator strength, we obtain estimates for the intermolecular electronic coupling and its exponential decay coefficient. © 2010 American Institute of Physics.
