Abstract
Quantum tunneling (QT) is not an effect often considered in chemistry, and rightfully so. However, in many cases it is significant, and in some cases it is even considerable. In this chapter we will describe the basic tenets of QT with a focus on catalysis, followed by some of the most important tools to study and compute them. The chapter goes on to address the title of the chapter by discussing several clear cases of QT for hydrogen-based reactions in organometallic, enzymatic, astrochemical, and organic systems. The insights highlighted in the chapter showcase the importance of QT in specific catalyzed reactions and help uncover the instances that are worth of attention.
