Abstract
The chapter is a summary of ultrafast time-resolved pumpprobe spectroscopy techniques for the study of charge carriers in organic semiconductors. Four methods featuring sub-nanosecond time resolution are distinguished according to their probe wavelength: infrared active vibrational (IRAV) mode spectroscopy, time-resolved THz spectroscopy (TRTS), time-resolved microwave conductivity (TRMC), and transient photocurrent (TPC) spectroscopy. Examples of the application of these techniques to the study of charged photoexcitations in molecular crystals, pristine polymers and ...
