The inherently low signal-to-noise ratio of NMR and MRI is now being addressed by hyperpolarization methods. For example, iridium-based catalysts that reversibly bind both parahydrogen ligands in solution can hyperpolarize protons (SABRE) or heteronuclei (X-SABRE) on a wide variety ligands, using complex interplay spin dynamics chemical exchange processes, with common signal enhancements between 10 3 4 . This does not approach obvious theoretical limits, further enhancement would be valuable...

The connection between the adiabatic excitation energy of time-dependent density functional theory and ground state correlation from fluctuation-dissipation theorem (ACFDT) is explored in limiting case one excited state. An exact expression derived for any Hartree-exchange-correlation kernel that connects potential contribution to correlation. resulting formula applied asymmetric Hubbard dimer, a system where this limit exact. Results hierarchy approximations kernel, including random phase...
