For Ph.D. students and others interested in chemical and biological
charge transfer, and with an urge to approach charge transfer
concepts and formalism beyond the trivial.
Contents: established and frontier elements of electron and atom
group transfer in chemistry, biochemistry and biophysics. See
course description.
Læringsmål:
En studerende, der fuldt ud har opfyldt kursets mål, vil kunne:
Have indsigt i kemiske redoxprocesser, elektrokemiske processer
og biologiske elektrontransportprocesser.
Forstå disse bredt optrædende processer som fundamentale
kvantemekaniske elektrontransportfænomener.
Være bekendt med basale elementer af kvantemekanisk og
statistisk mekanisk teori, herunder den kvantemekaniske
tunneleffekt.
Forstå og beskrive det omgivende reaktionsmediums betydning i
kemisk og biologiske processer.
Have indsigt i de vigtigste elementer af kemisk og biologisk
elektrontransportteori.
Kunne foretage beregninger af kemiske, elektrokemiske og
biologiske hastighedskonstanter og vurdere de indgående
procestypers egenskaber i relation hertil på basis af molekylær
elektrontransportteori
Være bekendt med formalisme og begreber inden for andre
molekylære elektriske ladningstransportfænomener som
protontunneleffekt, kinetiske isotopeffekter, optisk induceret
elektronoverførsel, elektronhop over store afstande m.m.
Forstå, beskrive og anvende elektrontransportbegreber i
scanning tunnel mikroskopi og andre nye nanoteknologiske
elektrontransportsystemer.
Kursusindhold:
Established and frontier elements of electron and atom group
transfer in chemistry, biochemistry and biophysics. Topics to be
chosen from:
1.The quantum mechanical tunnel effect in physical, chemical, and
biological systems.
2.The liquid state of the environmental reaction medium.
3.The simplest chemical process - electron transfer: outer sphere
electron transfer in inorganic and organic chemistry; dissociative
electron transfer.
4.Towards preciser electron transfer theory: nuclear tunnelling;
chemical processes at low temperatures; the diabatic and adiabatic
limits.
5.Optical electronic processes and charge transfer spectroscopy.
6.Proton and atom group transfer: general acid and base catalysis,
kinetic isotope effects.
7.The electrochemical process: the solid-liquid interface; electron
transfer at metal and semiconductor electrodes; electron densities
and electron tunnelling.
8.The notion of "long-range" electron transfer;
intermediate states and intermediate matter; environmental dynamics
and electron tunnelling.
9.Electron transfer in proteins and nucleic acids: molecular
recognition; coherent processes; the photosynthetic apparatus;
enzyme function and conformational dynamics.
10.Solvation and resolvation dynamics - the stochastic approach.
11.Perspectives and outlook: chemical nanostructures; molecular
electronics; scanning probe microscopy, STM and AFM; ultrafast
processes; charge transfer and phase transitions.
