The unequal treatment of space and time in quantum mechanics has many ramifications, particularly when we begin to ask questions about \textit{when} and \textit{where} a particular event occurs. The implications of this have been explored extensively in the quantum gravity literature and in fields related to the foundations of quantum mechanics. However, the unequal treatment of space and time in quantum chemistry and condensed matter physics has hardly been explored to date.   I propose a research program that will explore the meaning of time in chemical systems. My group will explore questions such as: What is a chemical event? How can we define a clock to measure when a chemical event occurs? What are the conditions under which it is valid to treat time as a parameter and not a dynamical variable? Can the role of time in chemistry teach us about the meaning of time in other fields such as quantum gravity? To better understand these questions, we will explore four three  broad areas of research, outlined in the sections below. %For instance, the position of an event and the momentum exchanged during an event cannot both be measured with infinite precision, as a consequence of canonical commutation relations between the position and momentum operators. Although time and energy satisfy an uncertainty principle as well, time is treated as a parameter and therefore no canonical commutation relations with the Hamiltonian exist. Another implication of the unequal
