Flavin adenine dinucleotide (FAD) is an important cofactor in many light-sensitive enzymes. The role of the adenine moiety of FAD in light-induced electron transfer was obscured, because it involves an adenine radical, which is short-lived with a wea

Assessment of heteronuclear long-lived states at ultralow magnetic fields

Autor: Ivan V. Zhukov, Alexandra V. Yurkovskaya, Konstantin L. Ivanov, Alexey S. Kiryutin

Publikováno v: Physical Chemistry Chemical Physics. 21:18188-18194

A study of long-lived spin states in hetero-nuclear spin systems is presented. Since long-lived states are efficiently sustained only when the spins are "strongly coupled", this study necessitates going to "ultralow" magnetic fields, which are much l

A novel method dubbed ZULF-TOCSY results from the combination of Zero and Ultra-Low Field (ZULF) with high-field, high-resolution NMR, leading to a generalization of the concept of total correlation spectroscopy (TOCSY). ZULF-TOCSY is a new building

Photochemically induced dynamic nuclear polarization (photo-CIDNP) is a method to hyperpolarize nuclear spins using light. In most cases, CIDNP experiments are performed in high magnetic fields and the sample is irradiated by light inside a nuclear m

Strong coupling of nuclear spins, which is achieved when their scalar coupling 2πJ is greater than or comparable to the difference δω in their Larmor precession frequencies in an external magnetic field, gives rise to efficient coherent longitudin

Chapter 23. Singlet Order in Heteronuclear Spin Systems

Autor: Alexandra V. Yurkovskaya, Dmitry Budker, Alexey S. Kiryutin, Ivan V. Zhukov, Konstantin L. Ivanov

The concept of heteronuclear Long-Lived spin States (LLSs) is introduced. In the simplest case of a pair of heteronuclei, such states are given by the singlet order of the spin pair, which can be efficiently sustained under Zero or Ultra-Low Field (Z
