Poštovani kolege,
Idući tjedan posjetit će nas Dr. Steffen Krämer iz NMR laboratorija u
Grenoblu. Tijekom posjeta održat će niz od 5 dvosatnih predavanja (svaki dan
23.-27. Siječnja) o NMR-u: od osnova metode do primjena u fizici čvrstog
stanja. Sažetak je priložen ispod ovog maila, a primjeri će biti iz čvrstog
stanja.
Predavanja su svaki dan 14-16h u seminaru teorijske fizike, Bijenička 32,
drugi kat, soba 201.
Naš gost, dr, Krämer bio je student i doktorand profesora Michaela Mehringa
u Stuttgartu, a danas vodi high-field-high-resolution NMR projekt u
Grenoblu. Niz predavanja u siječnju bit će koristan svima koji se žele
baviti NMR-om ili barem razumjeti eksperimentalne rezultate i mogućnosti
metode. Vjerujem da će ga moći pratiti studenti četvrte i pete godine
diplomskog studija, a posebno studenti poslijediplomskog studija, kao i
postdoktorandi.
Studenti doktorskog studija kondenzirane tvari koji će redovito pohađati
predavanja, dobit će potvrdu o pohađanju s kojom će moći podnijeti molbu za
priznavanje dijela ECTS bodova.
Srdačan pozdrav,
Miroslav Požek

Workshop: Concepts of pulsed nuclear magnetic resonance spectroscopy
Nuclear Magnetic Resonance (NMR) is one of the most outstanding cases, where
innovations of methods established the basis for one of the most powerful
spectroscopy techniques with manifold applications comprising physics,
chemistry, biology and medicine. Despite these different fields of
application one can nevertheless find a common core that describes the basic
NMR concept: Interacting nuclear spin ensembles are manipulated in a
coherent way according to basic laws of quantum mechanics. In this workshop
this fundamental concept will be elaborated using selected examples of NMR
spectroscopy.
Tentative topics:
• NMR and quantum mechanics
o Introduction
o Phenomenological NMR: classical movement of a magnetic moment
o Spin-1/2 and quantum mechanics of a two level system
o Operator formalism
o Density operator and Liouville formalism of pulsed NMR
• Application of Liouville formalism to pulsed NMR
o The Free Induction Decay (FID)
o Spin echo and the concept of phase cycling
o Effective spin-1/2 formalism: the case of Nuclear Quadrupole Resonance
(NQR)
o Interacting spins
• Option: Technical issues
o Signal-to-Noise Ratio of NMR
o NMR coils and probes
o Elements of a pulsed NMR spectrometer
o Quadrature detection of NMR
