High-field ESR offers many advantages in exploring fundamental questions of structure and dynamics in chemical, biological and physical samples. We provide a review of recent work performed at ACERT demonstrating the utility and flexibility of our methods for extracting both qualitative and quantitative information from a variety of systems. In particular, we emphasize the utility of multi-frequency ESR techniques for unraveling the details of the complex dynamical modes of proteins in solution and in heterogeneous systems such as lipid bilayers. We also include indications of directions for future work where appropriate.
