The structure of the secondary radical pair, , in fully deuterated and Zn-substituted reaction centers (RCs) of the purple bacterium Rhodobacter sphaeroides R-26 has been determined by high-time resolution and high-field electron paramagnetic resonan

Electron paramagnetic resonance (EPR) and related spectroscopic tools remain among the most important probes of structure and function of natural photosynthetic systems. Indeed, the challenging questions in the study of photosynthesis have to a great

The spin-polarized W-band EPR spectra of the secondary radical pair in plant photosystem I indicate a magnetic-field-induced orientation of the photosynthetic reaction centers in the field of the EPR spectrometer. This orientation arises due to the a

The first compound for which the previously predicted biaxial nematic phase was claimed is 4-[3,4,5-tris(4-dodecyloxybenzyloxy)benzoyloxy]-4′-(4-dodecyloxybenzoyloxy)-1, 1′-biphenyl (I). This assignment was based on the observation of the optical

The effect of rotating the nematic phase of 4-n-pentyl-4′-cyanobiphenyl (5CB) at a frequency ωr about an axis perpendicular to an applied magnetic field has been studied using deuterium NMR spectroscopy. The alignment of the directors produced by

Results of transverse 31 P and 2 H relaxation measurements in dimyristoyl-phosphatidylcholine membranes employing the Carr-Purcell-Meiboom-Gill pulse sequence are reported. The observed pulse frequency dependence indicates the existence of slow motio

We report the results of a study of the properties of the paramagnetic triplet state of eosin Y and erythrosin. This information is a prerequisite for their use as EPR probes. The magnetic anisotropy in both molecules is found to be suitable for moni
