Quadrupole coupling tensor in deuterated benzenes
Deuterium quadrupole coupling tensors in deuterated
benzenes have been studied both experimentally by NMR spectroscopy in
Liquid Crystal (LC) solvents and theoretically by ab initio
electronic structure calculations. The results are presented in the

Structure determination of flavonoids
Principles of structure determination of flavonoids using NMR- and
HPLC-MS/MS -methods. How to integrate the information
originating from different experimental methods and how to resolve
structure of different flavonoids? I will present the
principles using examples.
27.4. Jouni Karjalainen
Parallelization of Monte Carlo molecular simulations
Algorithms for the parallelization of Monte Carlo molecular simulations
are reviewed. Possible uses, scalability and efficiency of different
algorithms is discussed.

coefficient of 129Xe nuclear shielding revisited
Few aspects in the theoretical calculation of the second virial
coefficient of 129Xe nuclear shielding are pondered. The
accuracy of final theoretical second virial coefficient curve is
compared to the experiment throughout the temperature range. The
reasons for the remaining deviations are discussed.

relativistic effects on Xe chemical shift.
main relativistic effects on Xe chemical shift in various chemical
environments are discussed. In all systems under discussion, they are
shown to arise from five distinct physical contributions of the
Breit-Pauli perturbation theory (BPPT). While being heavily dependent on
electron correlation, they provide an excellent example of
cross-coupling of relativity and electron correlation.

Spin-lattice relaxation of inert gases in porous materials
It has been observed that the spin-lattice
relaxation times of fluorine nuclei in gases such
as sulfur hexafluoride confined to pores are
strongly dependent on the pore size. A
theoretical description of this phenomenon is discussed.

Studies of Bioactive Compounds Produced by Endophytic Methylobacterium of Scots
Internal plant microbes, endophytes, have during the recent years
become in the spotlight of research. Endophytes are essential for
plant defense, and numerous reports point to action of endophytes in
plant growth and development. The Methylobacterium endophytes affect
morphology and extend viability of Scots pine tissues through
bioactive products. Infection of pine seedlings by the
Methylobacterium endophytes increases lateral root formation, root
length, and biomass. The biological significance of the
Methylobacterium endophytes is mainly unknown

spin-lattice relaxation measurements of SF6 confined in
The inversion recovery method
was used to study the 19F -relaxation of SF6 in
porous materials. Various other methods were used to determine the
pressure and the absorption of the samples to achieve a more
comprehensive understanding of the physics behind the behaviour of the
relaxation. Latest aspects and results will be presented in the talk.
9.11. Anne Räty
dissolved in liquid crystals with the variable angle spinning (VAS)
In the presentation I will talk about my
research with liquid crystals. Spectra and some of the analyses from
my studies with Phase5 and Felix-R&D are discussed.

additive approximation in xenon clusters
Pairwise additive approximation in small xenon clusters is introduced
in the calculation of xenon NMR properties. Some results for the
chemical shift are shown.

NMR Parameters in Water Dimer
NMR parameters in water dimer are monitored as the dimer geometry is
systematically changed. The behavior is displayed as NMR "property
surfaces", followed by a discussion of the main trends.

GMR - a.k.a what
you have to do to win a Nobel prize?
overview on Giant MagnetoResistance (GMR) and its applications. The
GMR phenomenon was discovered in the late 80s by the groups of Albert
Fert and Peter Grunberg and they were awarded the "Nobel prize in
physics 2007" for their discovery.
