      abstract     = {We report a comparison of modulation of intensity with zero
                      effort (MIEZE), a neutron spin–echo technique, and neutron
                      time-of-flight (ToF) spectroscopy, a conventional neutron
                      scattering method. The evaluation of the respective recorded
                      signals, which can be described by the intermediate
                      scattering function I(Q, τ) (MIEZE) and the dynamic
                      structure factor S(Q, E) (ToF), involves a Fourier
                      transformation that requires detailed knowledge of the
                      detector efficiency, instrumental resolution, signal
                      background and range of validity of the spin–echo
                      approximation. It is demonstrated that data obtained from
                      pure water align well within the framework presented here,
                      thereby extending the applicability of the MIEZE technique
                      beyond the spin–echo approximation and emphasizing the
                      complementarity of the two methods. Computational methods,
                      such as molecular dynamics simulations, are highlighted as
                      essential for enhancing the understanding of complex
                      systems. Together, MIEZE and ToF provide a powerful
                      framework for investigating dynamic processes across
                      different time and energy domains, with particular attention
                      required to ensure identical sample geometries for
                      meaningful comparisons.},
