Distributed Information Services in Physics
No full textThe concept of distributed information services maintained by a distributed work force for scientific information is described. Realizations and experiences for Physics (since 1995), Marine Sciences, and dissertation theses in physics are presented. Technically the information is gathered from the local web servers of the worldwide distributed research institutes and departments, by distributed Harvest-gatherers, under the control of national learned societies or regional other institutions. Queries are answered by a network of mirrors of Harvest-brokers. For PhysNet, a Charter sets the rules to assure a noncommercial, free full-text access service, under the control of the set of national national learned societies involved, but unbiased to any single one

Hydrogen bonded rings, chains and lassos: the case of t-butyl alcohol clusters
No full textInfrared OH stretching spectra of hydrogen bonded 2-methyl-propan-2-ol (t-butyl alcohol) clusters are investigated by ragout-jet FTIR spectroscopy. A spectral difference technique is used to discriminate approximately between neighbouring cluster sizes. Dimers, trimers and cyclic tetramers can be detected along with larger clusters, which exhibit a surprisingly structured vibrational fingerprint. Comparison is made to the spectra of related alcohols and to energetic and harmonic vibrational predictions from electronic structure calculations. The experimentally observed 32% increase in OH stretching wavenumber shift from methanol dimer to t-butyl alcohol dimer is reproduced at the HF/3-21G level (+33%). It is also qualitatively correct at the MP2/6-311G level (+15%), whereas it has the wrong sign at the B3LYP/6-311G level (-5%) and is negligible at the HF/6-311G level, disregarding anharmonic effects. The cyclic tetramer of t-butyl alcohol is found to be particularly stable due to a favourable up-down alternation of the bulky t-butyl groups. Beyond the t-butyl alcohol tetramer, lasso structures are found to be energetically competitive with simple ring structures. A many-body decomposition shows that this is due to a reduced cooperativity in the sterically hindered pentamer ring. The resulting thermodynamic and kinetic relevance of cyclic tetramers is discussed
