Title: Quantitative two-dimensional EXSY spectroscopy and dynamic behavior of a paramagnetic lanthanide macrocyclic chelate: YbDOTA (DOTA = 1,4,7,10-tetraazacyclododecane-N,N{prime},N{double_prime},N{double_prime}{prime}-tetraacetic acid)

The chelate, YbDOTA (DOTA = 1,4,7,10-tetraazacyclododecane-N,N{prime},N{double_prime},N{double_prime}{prime}-tetraacetic acid) has two possible conformations. Interconversion between isomers was studied by EXSY NMR spectroscopy. The activation energy for conversion was found to be 65.6 kJ/mol for conversion from the major to the minor species.
