The long-range forces in molecules and polymers Any theory kaantowa regular polymers i. Any theory of regular polymers i. The ground state electronic energy represents a complicated function of the nuclear coordinates.

Lucjan Piela and Leszek Stolarczyk pointed out that most multipole expansion applications reported in the literature were coordinate-system dependent.

According to that hypothesis some donor-acceptor oligomers may exhibit long-living isomeric electronic metastable states. He loves to paint, see the attached paintings. Professor Piela serving as a dean of the Chemistry Department of the University of Warsaw has introduced profound changes described in L. A47, E. The idea of deformation is based on a destabilisation of all minima of a function by introducing smoothing techniques Diffusion Equation Method, DEM, distance scaling method, shift method, also related to them: His achievements were widely recognized by the scientific community.

Today 61 8. It turned out that a small protein of 32 amino acids, with carefully predesigned amino acid sequence, exhibits indeed such an effect, which may be seen as a model of the prion disease propagation. Strategies and Applications in Quantum Chemistry, edited by Y. After World War II he quickly completed high-school education and entered the University of Poznan to study chemistry and physics. Scheraga, Biopolymers,27, The isomers will differ by the electronic charge distribution rather than the nuclear framework as all the others do.

On some pecularities of intermolecular and intramolecular interactions. This leads to identifying the parameter t as time even for mathematical functions to be minimised with no relation to physics or chemistry. These were seminal theoretical developments never before attempted for any molecule. B 22, ]. His research topic was the influence of hindered rotation on neutron scattering off small organic molecules. Initially he employed the explicitly correlated basis introduced earlier by James and Coolidge.

Uniwersytet Warszawski, Pracownia Chemi Kwantowej ul. Piela with his collaborators explained this phenomenon by showing why the gap plays so critical role in the range of exchange interaction [L. The challenge to find this conformation from a given sequence of amino acids is known as a “second genetic code”. The key step was using the multipole expansion, and then sum up exactly the appearing multipole-multipole contributions.

His brave fight with the disease lasted for over one year. His premature death left those who knew and admired him in a deep sense of loss.

This work established important theoretical limits on the possible yield of muonic catalysis and contributed significantly to our understanding of this phenomenon. Renewed interest in this field arose in the s when new experiments indicated that a single muon can catalyze hundreds of fusion reactions.

Professor Piela and Anna Jagielska have proved by ab initio calculations that indeed in some substances a single chemiw transfer requires a considerable amount of energy, while a few such transfers need negligible energy.

A42, B. When the energy band gap is non-zero, the exchange energy is of the short-range, while for the zero gap i. His early papers on the correlation of electronic motion in the ethylene and benzene molecules contained important ideas on this subject, later developed further by himself and others. Together with his collaborators from Warsaw, he studied the foundations of the perturbation theory of intermolecular forces and contributed to the development of the current formulation of the symmetry-adapted perturbation theory.

Sciences USA, Main scientific activity of Professor Piela is focused in three domains: Selected other publications L. The strategy behind the deformation was the following: S15, L. The obtained modified multipole expansion gave results invariant also with respect to the arbitrary choice of the unit cell.

S14, J. Bruxelles 92, J.

He received his bachelor degree in in his home town Rzeszow from the years old Konarski College. This is why predicting the lowest-energy conformation chejia configuration represents a formidable task.

He also devoted considerable effort to the study of various spectroscopic properties of excited states of the hydrogen molecule obtaining numerous accurate potential energy curves which have been invaluable not only in interpreting spectroscopic experiments, but also in other fields of science. When discussing the contributions to the conformational chemix the importance of the hydrophobic effect as well as of the electrostatic interactions has been stressed.

Letters 15, L. Professor Piela together with Leszek Piella proposed in a new kind of isomers. In particular it turned out that the dipole moments of kwantwa NH and of the CO bonds in proteins functioning in nature are oriented to good accuracy along the local intramolecular electric field.

Lucjan Piela is the author of about hundred papers published in international journals. Piela Delta 7, 3 L.

Another article, published in also with Wolniewicz, was listed as one of the one hundred most cited articles which appeared in the Reviews of Modern Physics. Special issue of Polish Journal of Chemistry Pol. In he received an honorary doctorate from his Alma Mater: USA, 90, As shown by other authors the DEM method is related to several equations of physics:
