Pivotal role of 99Tc NMR spectroscopy in solid-state and molecular chemistry

Abstract

The radioelement Technetium (element 43) pertains to various domains including the nuclear enterprise (i.e., spent nuclear fuel (SNF) reprocessing and nuclear waste remediation) and nuclear medicine (i.e., development of new imaging agents) as well as to the fundamental science of transition metals (i.e., chemical trends in catalytic properties). One method that can provide critical information to improve knowledge in these domains is 99Tc nuclear magnetic resonance (NMR) spectroscopy. The review, presented here, summarizes the pivotal role of 99Tc NMR spectroscopy over the past two decades and presents prospects of the method to tackle challenges in Tc chemistry. The radioelement technetium is central in spent nuclear fuel reprocessing and waste remediation, the development of new imaging agents, as well as in fundamental science of transition metals. Here, the authors review the pivotal role of 99Tc NMR spectroscopy over the past two decades and present prospects of the method to tackle challenges in Tc chemistry.
