The bridge methylene protons have a large hyperfine coupling constant (2.46 mT) and show second-order interaction both in the ESR and ENDOR spectra. The relative signs of the coupling constants were obtained using triple resonance. The observed ENDOR second-order splitting (0.009 mT) together with the line positions are in complete agreement with theoretical prediction. © 1984.  ISSN : 0009-2614  Journal Name : Chemical Physics Letters  Volume : 109  Issue Number : 4  Publishing Year : 1984 AH 1984 AD  Number Of Pages : 5  Article Type : Article  Added Date : Monday, October 19, 2009  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email Evans, J.C Evans, J.C Researcher Doctorate   عبدالله يوسف عبدالله عبيد Abdullah Yousif Obaid Researcher Doctorate aobaid@kau.edu.sa Rowlands, C.C Rowlands, C.C Researcher Doctorate   Files File Name Type Description  23227.pdf pdf Abstract Back To Researches Page
