As will be shown, by considering the residuals between the two spin components of (anti)aromaticity, we rationalize features of the heteroaromatics in their n,* states, e.g., when these states are the lowest excited states. Hence, we provide a theoretical framework for the (anti)aromatic character of n,* states that can be generalized to states with even and odd -electron counts (or vice versa). We pinpoint why excited state (anti)aromaticity investigations require both quantitative computations and qualitative theory if one is to arrive at conclusions that are correct and comprehensive. Such fundamental knowledge should allow for more insightful design of molecules with targeted properties and applications, especially if linked to machine-learning approaches.
