C - and Proton - ENDOR Studies of 13 C - labelled Organic Radicals
نویسنده
چکیده
As part of a systematic non-proton ENDOR-in-solution study results are reported for 13C in several isotopically enriched model compounds. Methods for synthesizing these labelled compounds are also presented. The optimum 13C ENDOR temperatures are found to be considerably higher than for protons on account of the larger hyperfine anisotropy. Cross relaxation effects are used to determine rotational correlation times. The isotropic 13C hyperfine couplings are in satisfactory agreement with INDO results.

Determination of the g tensors for the dominant stable radicals in X-irradiated beta-D-fructose single crystals.
In spite of recent successful identifications of radicals produced after X-ray irradiation at 10 and 77 K in beta-D-fructose, the structure of the two stable radicals dominating the electron paramagnetic resonance (EPR) spectrum after room temperature irradiation is still unclear. Based on the agreement between proton hyperfine (HF) tensors obtained in electron nuclear double resonance (ENDOR) ...
متن کاملThe Use of 13C in the Synthesis of Double Labelled Precursors
Discovery of 13C NMR and its application in the biosynthetic pathways prompted the synthesis of several 13C labelled precursors. To investigate the metabolism of phenyllactic acid in the Solanaceae family, the double labelled acid was synthesized from barium carbonate (13C) and sodium syanide (13C)
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...
متن کاملIdentification of primary free radicals in trehalose dihydrate single crystals X-irradiated at 10 K.
Primary free radical formation in trehalose dihydrate single crystals X-irradiated at 10 K was investigated at the same temperature using X-band Electron Paramagnetic Resonance (EPR), Electron Nuclear Double Resonance (ENDOR) and ENDOR-induced EPR (EIE) techniques. The ENDOR results allowed the unambiguous determination of six proton hyperfine coupling (HFC) tensors. Using the EIE technique, th...
متن کاملProton-Electron Hyperfine Coupling Constants of the Chlorophyll a Cation Radical by ENDOR Spectroscopy
In this paper we describe the assignment of the major coupling constants in monomer chlorophyll a cation free radical by ENDOR spectroscopy. To facilitate chemical manipulation methylpyrochlorophyllide a has been used as a stand-in, and a suite of six selectively deuterated derivatives have been subjected to ENDOR investigation. Details of the synthesis of these compounds are described. To stud...
