Long-lived states: some unexpected applications
During the 42nd session of the Global NMR Discussion Meetings held on February 8th, 2022 via Zoom, Prof. Geoffrey Bodenhausen gave a talk on the topic "Long-lived states: some unexpected applications". The recording serves as a tutorial.
Abstract: The invention of singlet states, also known as long-lived states (LLS), by Malcolm Levitt was to be followed by many further inventions by scores of creative co-workers in Southampton and Novosibirsk: the quest for molecules immersed in environments capable of supporting singlet states with very long lifetimes, magnetization-to-singlet conversion (M2S), extremely low frequency (ELF) excitation, classification of decay rates according to the eigenvalues of the Liouvillian, effects of exchange on the lifetimes of LLS, etc. Our laboratories at EPFL and ENS have focused on a few applications of long-lived states, such as the study of slow diffusion of macromolecules, long-lived states in substrates of enzymatic reactions, long-lived states in systems with many spins, long-lived population imbalances in systems containing quadrupolar nuclei, elusive long-lived states in water (“para-water”), and long-lived states in drug molecules binding to macromolecular targets.
