Enhanced sensitivity of electron-nuclear double resonance (ENDOR) by cross polarisation and relaxation.
Electron-nuclear double resonance (ENDOR) is a method of choice to detect magnetic nuclei in the coordination sphere of paramagnetic molecules, but its sensitivity substantially suffers from saturation effects. Recently we introduced a new pulsed ENDOR experiment based on electron-nuclear cross polarisation (CP) transfer. Here we analyse the time evolution of the spin polarization in CP-ENDOR a...
متن کاملPolarisation Signals
Humans are fascinated by the colour vision, colour signals and ‘dress codes’ of other animals as we can see colour. This property of light may be useful for increasing the contrast of objects during foraging, defence, camouflage and sexual communication. New research, largely from the last decade, now suggests that polarisation is a quality of light also used in signalling and may contain infor...
متن کاملPolarisation vision
adhesion proteins implicated in integrin activation, including integrin-linked kinase and the filamin-binding protein, migfilin (Figure 1). However, whether these interactions are important for activation or for kindlin-mediated integrin signaling, focal adhesion formation, and cell spreading is unclear and elucidation of the mechanisms of kindlin function will likely require detailed knowledge...
متن کاملDynamic nuclear polarization in pulsed ENDOR experiments.
Properly prepared pulse sequences of microwave and radio frequency have been employed to investigate the effect of polarization transfer from the polarized photo excited triplet state of pentacene in p-terphenyl crystals to the surrounding protons in pulsed ENDOR experiments. The ENDOR signal, measured as the change of electron spin echo (ESE) amplitude, is affected by the mode of RF pulses. Wh...
متن کاملENDOR studies of substituted chlorophyll cation radicals
Cation radicals of substituted chlorophyll (Chl) a molecules were characterized by EPR and ENDOR spectroscopy. The effect of substitutions of the vinyl group at position 3 and the carbomethoxy group at 13 as well as the replacement of the central magnesium atom by zinc were investigated. All major hyperfine coupling constants could be determined and assigned to specific molecular positions. Com...
