We report progress with an old problem in magnetic resonance—that of the exponential scaling of simulation complexity with the number of spins. It is demonstrated below that a polynomially scaling algorithm can be obtained (and accurate simulations p...

Spin relaxation effects in photochemically induced dynamic nuclear polarization spectroscopy of nuclei with strongly anisotropic hyperfine couplings (2007)
Journal Article
Kuprov, I., Craggs, T., Jackson, S., & Hore, P. (2007). Spin relaxation effects in photochemically induced dynamic nuclear polarization spectroscopy of nuclei with strongly anisotropic hyperfine couplings. Journal of the American Chemical Society, 129(29), 9004 -9013. https://doi.org/10.1021/ja0705792

We describe experimental results and theoretical models for nuclear and electron spin relaxation processes occurring during the evolution of 19F-labeled geminate radical pairs on a nanosecond time scale. In magnetic fields of over 10 T, electron-nucl...

We describe a general method for the automated symbolic processing of Bloch-Redfield-Wangsness relaxation theory equations for liquid-phase spin dynamics in the algebraically challenging case of rotationally modulated interactions. The processing typ... Read More about Bloch-Redfield-Wangsness theory engine implementation using symbolic processing software.

Bidirectional electron transfer in photosystem I : determination of two distances between P700+ and 1- in spin-correlated radical pairs (2005)
Journal Article
Santabarbara, S., Kuprov, I., Fairclough, W., Purton, S., Hore, P., Heathcote, P., & Evans, M. (2005). Bidirectional electron transfer in photosystem I : determination of two distances between P700+ and 1- in spin-correlated radical pairs. Biochemistry, 44(6), 2119-2128. https://doi.org/10.1021/bi048445d

The spin-correlated radical pair [P700+A1-] gives rise to a characteristic "out-of-phase" electron spin-echo signal. The electron spin-echo envelope modulation (ESEEM) of these signals has been studied in thylakoids prepared from the wild-type strain...

Chemically induced dynamic nuclear polarisation (CIDNP) is explored as a source of nuclear hyperpolarisation in heteronuclear Overhauser effect experiments. A photochemical reaction proceeding through a radical pair intermediate is used to enhance 19... Read More about Chemically amplified ¹⁹F-¹H nuclear Overhauser effects.
