Trityl radicals: spin labels for nanometer-distance measurements.
Spin labelling with trityls: to gather information about the structure and dynamics of trityl radicals, spin-labelled polymers were measured with pulsed electron-electron double resonance (PELDOR) and double-quantum coherence (DQC). This study demonstrates that trityl radicals have great potential as spin labels that eliminate some limitations of nitroxide spin labels.
متن کاملMeasurements of short distances between trityl spin labels with CW EPR, DQC and PELDOR.
Trityl based spin labels are emerging as a complement to nitroxides in nanometer distance measurements using EPR methods. The narrow spectral width of the trityl radicals prompts us to ask the question at which distance between these spin centers, the pseudo-secular part of the dipolar coupling and spin density delocalization have to be taken into account. For this, two trityl-trityl and one tr...

متن کاملInteraction between spin labels and DPPC vesicles.
1H NMR studies on DPPC vesicles labeled with the spin labels (1,14) or (12,3) have shown that both of the spin labels influence the fatty acid side chains as well as the choline head groups. The spin label (12,3) affects, naturally, the head groups stronger than the spin label (1,14), while the reversed effect can be observed at the side chains. This effect progresses with time after vesicle pr...
متن کاملHigh-field electron spin resonance of spin labels in membranes.
High-field electron spin resonance (ESR) spectroscopy is currently undergoing rapid development. This considerably increases the versatility of spin labelling which, at conventional field strengths, is already well established as a powerful physical technique in membrane biology. Among the unique advantages offered by high-field spectroscopy, particularly for spin-labelled lipids, are sensitivi...
