Molecules with high internal energy (AB*) can undergo decay by ionization (AB<sup>+</sup>+e<sup>–</sup>) or dissociation (A+B). With high-resolution chirped-pulse microwave spectroscopy, we can obtain detailed information about molecular structure that reveals
the underlying decay mechanisms and provides insight into these fundamental chemical processes. In this talk, I will describe recent work on Rydberg states of nitric oxide (NO) – electronic states in which a single electron is excited to a high-energy, hydrogen-like
orbital. We have made new measurements of the electric properties of the NO<sup>+</sup> ion and developed a mechanistically explicit model for ionization of these unique Rydberg states. Based on these results, we propose a widely applicable method for generating
molecular ions with well-determined internal energy for use in cold, controlled chemistry studies.
