[NMR] International School for Young Scientists on Magnetic Resonance and Magnetic Phenomena

Dear colleagues,

We cordially invite you to participate in the VI International School for Young Scientists: Magnetic Resonance and Magnetic Phenomena in Chemical and Biological Physics, which will be held in Roshchino, St. Petersburg (Leningrad) region, Russia on September 5-10, 2020. 

The scope of the school is relatively broad, and its key purpose is to present interconnected topics in NMR and EPR spectroscopy in a form that underlines their fundamental similarity. Currently in several areas of research the two spectroscopies interconnect, thus building up new promising approaches, of which, probably, hyperpolarization and paramagnetic NMR are the most known and broadly used examples. We intend approaching the basic mechanisms responsible for the polarization transfer from electrons to nuclei both from NMR and EPR side. Similarities and differences in electron and nuclear relaxation and dipolar interactions will be in the focus of this school, as well.

The school includes lectures and tutorials on pulsed EPR, pulsed NMR, spin hyperpolarization and spin chemistry, including chemically induced spin polarization. A feature of the School is to approach these apparently different topics within a common theoretical framework, with the intention to obtain deeper understanding of spin dynamics of coupled electron-nuclear systems. Another aim of the School is to provide the participants with systematic knowledge of the mechanisms of the action of pulse sequences commonly used in modern EPR and NMR. We will also discuss in depth the interplay of electron and nuclear spins in modern EPR and NMR experimental methods. Furthermore, effects of electron and nuclear spins on chemical reactivity, playing a major role in spin chemistry, will be considered.

The program will include lectures and practical tutorials. The composition of the program will allow the participants to learn how to describe spin dynamics in pulse EPR and NMR experiments and, ultimately, to design novel magnetic resonance experiments. The meeting will be limited to 50 participants (not counting lecturers). The working language is English.

Registration deadline is 1 June 2020. Registration fee is 200 Euro for foreign participants and 12000 Roubles for Russian participants, which covers participation in all scientific sessions, coffee-breaks, welcome party, conference materials, cultural program, breakfast and lunch. For AMPERE members the fee is reduced.

The teachers are:

Christian Griesinger (Göttingen, Germany) 
Leonid Kulik (Novosibirsk, Russia)
Olivier Lafon (Lille, France)
P. K. Madhu (Hyderabad, India)
Kiminori Maeda (Saitama, Japan) 
Valentin Novikov (Moscow, Russia)
Maxim Yulikov (Zurich, Switzerland)

More information is available at the web-site of the School: http://roshchino2020.tomo.nsc.ru/
Please encourage your young colleagues to participate in this event.
Sincerely yours,

Prof. Konstantin Ivanov, co-chairmanProf. Leonid Kulik, co-chairman

1st International EPR-on-a-chip Workshop

EPR-on-a-chip is an emerging technology that aims at providing the analytical power of electron paramagnetic resonance (EPR) spectroscopy in the tiny form factor of a millimeter-sized microchip.

Within the BMBF sponsored research project EPRoC, the possibilities of this new and fascinating technology are evaluated in the context of operando EPR measurements on energy materials.

The goal of the 1st International EPR-on-a-chip Workshop is to serve as a forum for discussing the possibilities of the EPR-on-a-chip technology in other disciplines, including catalysis, biology and medicine.


The application of novel Ir-NHC polarization transfer complexes by SABRE #DNPNMR #SABRE

Hadjiali, Sara, Marvin Bergmann, Alexey Kiryutin, Stephan Knecht, Grit Sauer, Markus Plaumann, Hans-Heinrich Limbach, Herbert Plenio, and Gerd Buntkowsky. “The Application of Novel Ir-NHC Polarization Transfer Complexes by SABRE.” The Journal of Chemical Physics 151, no. 24 (December 28, 2019): 244201.


In recent years, the hyperpolarization method Signal Amplification By Reversible Exchange (SABRE) has developed into a powerful technique to enhance Nuclear Magnetic Resonance (NMR) signals of organic substrates in solution (mostly via binding to the nitrogen lone pair of N-heterocyclic compounds) by several orders of magnitude. In order to establish the application and development of SABRE as a hyperpolarization method for medical imaging, the separation of the Ir-N-Heterocyclic Carbene (Ir-NHC) complex, which facilitates the hyperpolarization of the substrates in solution, is indispensable. Here, we report for the first time the use of novel Ir-NHC complexes with a polymer unit substitution in the backbone of N-Heterocyclic Carbenes (NHC) for SABRE hyperpolarization, which permits the removal of the complexes from solution after the hyperpolarization of a target substrate has been generated.

DNP Mechanisms #DNPNMR

Kundu, Krishnendu, Frédéric Mentink‐Vigier, Akiva Feintuch, and Shimon Vega. “DNP Mechanisms.” In EMagRes, 295–338. American Cancer Society, 2019.


This article presents a comprehensive description of the spin dynamics underlying the main DNP mechanisms leading to nuclear signal enhancements in glassy amorphous solids containing free radicals. The emphasis of the article to derive quantum mechanically based formalisms that enable us to analyze experimental DNP data. After a short review of the history of DNP, rate equations of the eigenstate populations of static coupled electron–nuclear spin systems are introduced, based on their spin-Hamiltonians and including spin-lattice and cross-relaxation mechanisms. They are used to simulate the dynamics of small spin systems under microwave (MW) irradiation and the basic Solid Effect (SE), Cross Effect (CE), and Overhauser DNP (O-DNP) enhancement mechanisms are presented. These calculations are then extended to systems containing up to 10 spins and are used to calculate EPR, ELDOR, and DNP spectra. Plots showing the population of the eigenstates vs energy are used to demonstrate the conditions for the thermal mixing mechanism and the corresponding EPR and ELDOR spectra are discussed. Following these calculations, the electron spectral diffusion (eSD) and the indirect Cross Effect (iCE) numerical models are introduced and used to analyze EPR and DNP spectra of real samples. In the last section, the basic theory of magic angle spinning (MAS) DNP on small spin systems is summarized and the influence of the rotor events on the quasiperiodic steady-state DNP enhancements discussed. The origins of depolarization effects occurring when no MW is applied are described. Finally, the nuclear spin diffusion process inside the diffusion barrier is studied using multielectron and multinuclear calculations.
