We study function spaces that are related to square-integrable, irreducible, unitary representations of several low-dimensional nilpotent Lie groups. These are new examples of coorbit theory and yield new families of function spaces on Rd. The concrete realization of the representation suggests that these function spaces are useful for generalized time-frequency analysis or phase-space analysis.
