Intrachain diffusion processes play an important role in protein folding and function. In this chapter we discuss the application of triplet-triplet energy transfer to directly measure rate constants for intrachain contact formation in polypeptide chains. The photochemistry of triplet-triplet energy transfer is described, experimental prerequisites of the method are discussed, and a detailed description of the experimental protocols and data analysis is given.
