    "abstract": "We study classical energy-momentum ($E$-$m$) diagrams for rotational motion\nof dipolar asymmetric top molecules in strong external fields. Static electric\nfields, nonresonant linearly polarized laser fields, and collinear combinations\nof the two are investigated. We treat specifically the molecules iodobenzene (a\nnearly prolate asymmetric top), pyridazine (nearly oblate asymmetric top), and\niodopentafluorobenzene (intermediate case). The location of relative equilibria\nin the $E$-$m$ plane and associated bifurcations are determined by\nstraightforward calculation, with analytical results given where possible. In\ncases where analytical solutions cannot be obtained, we resort to numerical\nsolutions, while keeping a geometrical picture of the nature of the solutions\nto the fore. The classification we obtain of the topology of classically\nallowed rotor configuration space regions in the $E$-$m$ diagram is of\npotential use in characterization of energy eigenstates of the corresponding\nquantum mechanical problem.",
