CREATION OF NEARLY-EQUIVALENT NUCLEAR SPIN SINGLET STATES USING SPIN-LOCK INDUCED CROSSING

摘要

Methods and systems for Nuclear Magnetic Resonance (NMR) spectra of samples having unresolved peaks are described. The methods and systems allow for the creation nuclear spin singlet states in nearly-equivalent spin pairs, for example, using continuous spin-locking with a nutation frequency matched to the coupling strength between spins.
