Konstantin Ivanov intercontinental magnetic resonance seminar series started on April 8, 2020. It organises seminars on a range of topics in magnetic resonance covering NMR, EPR, hyperpolarisation, colour centres and optical pumping, and ZULF NMR. The emphasis of the talks are on both methods and applications and a perspective on the future of the field. The speakers include a wide range of scientists ranging from PhD students to post-doctoral fellows, to senior scientists.
Upcoming Talks:
October 9, 2026, Danil Markelov, ENS Paris, France, "Origin of collective long-lived spin order in aliphatic chains revealed by relaxation theory", Aliphatic chains are common structural elements in many organic molecules. In the context of NMR, methylene nuclear spin chains can show an unusual and useful property: they can support delocalized long-lived nuclear spin states and collective zero-quantum long-lived coherences with lifetimes much longer than T_1 and T_2 relaxation times. Although such long-lived states and coherences have already been observed experimentally, their physical origin and general structure have remained unclear. Here, we show that these long-lived modes can be understood directly from Redfield relaxation theory. They form a relaxation-protected subspace associated with the dominant dipole-dipole relaxation between geminal protons within individual methylene groups. This provides a general way to construct collective long-lived spin order in aliphatic chains of arbitrary length. More broadly, this framework connects long-lived spin order in aliphatic chains with collective many-body spin dynamics.
