Abstract
Sensitive probes are required for studying the biochemistry of Gd(III) contrast agents used in magnetic resonance imaging. We show that complexation of Gd(III) by diethylenetriamine-N,N,N′,N′,N”-pentaacetic acid (DTPA) in aqueous solution can be readily determined from the sharp 4f-f bands for free and bound Gd(III) in the range 270–282 nm, and, with greater sensitivity, from the associated magnetic-circular-dichroic spectra.
