Conformation of chiral molecules The rotational spectrum of 2 chloropropionic acid verfasst von Alberto Lesarri, Jens Uwe Grabow, Walther Caminati Abstract Reported here are measurements of the rotational spectra of two isotopologues 35 Cl and 37 Cl of one of the simplest chiral carboxylic acids, 2 chloropropionic acid.

Internal dynamics in organometallic molecules Rotational spectrum of CH 3 3 GeCl verfasst von Melanie Schnell, Jens Uwe Grabow Abstract The microwave spectra of CH 3 3 74 Ge 35 Cl and its isotopologues CH 3 3 72 Ge 35 Cl and CH 3 3 74 Ge 37 Cl have been studied in the frequency range from 3 24 GHz revealing the complex internal dynamics of this organometallic molecule with three internal rotors.

An extension of this analogy is given by the concept of soliton molecules 1 , opening up new perspectives in fundamental science as well as applications in optical technologies. The standard nonlinear Schrödinger equation does not contain a direct solution for a molecule soliton state, so that one needs additional prerequisite, such as the use of a dispersion managed fiber allowing stable propagation of double humped intensit...

Conformational preferences of chiral molecules Free jet rotational spectrum of 1 phenyl 1 propanol verfasst von Barbara M. Giuliano, Paolo Ottaviani, Laura B. Favero, Walther Caminati, Jens Uwe Grabow, Anna Giardini, Mauro Satta Abstract The rotational spectra of normal and O d species of the two most stable conformers of chiral 1 phenyl 1 propanol, obtained by free jet millimetre wave absorption spectroscopy reveal that both conforme...

Soliton Molecules with Two Frequencies verfasst von Oliver Melchert, Stephanie Willms, Surajit Bose, Alexey Yulin, Bernhard Roth, Fedor Mitschke, Uwe Morgner, Ihar Babushkin, Ayhan Demircan Abstract We demonstrate a peculiar mechanism for the formation of bound states of light pulses of substantially different optical frequencies, in which pulses are strongly bound across a vast frequency gap.

Heteronuclear Two Frequency Soliton Molecules verfasst von Oliver Melchert, Stephanie Willms, Surajit Bose, Uwe Morgner, Ihar Babushkin, Ayhan Demircan Abstract We present novel robust bound states consisting of distinct components.

A single molecule reaction cascade First principles molecular dynamics simulation verfasst von Irmgard Frank Abstract The success of mechanochemistry is continued with the targeted organic synthesis of functional nano scale devices.

Conductance through single biphenyl molecules Symmetric and asymmetric coupling to electrodes verfasst von Karthiga Kanthasamy, Herbert Pfnür Abstract The contacts and the chemical bonds formed between metallic electrodes and molecules determine to a large extent the conductive properties of single molecular junctions, which represent the smallest possible active elements in an electronic circuit.

Highways for water molecules Interplay between nanostructure and water vapor transport in block copolymer membranes verfasst von Faheem Hassan Akhtar, Hakkim Vovushua, Luis Francisco Villalobos, Rahul Shevate, Mahendra Kumar, Suzana Pereira Nunes, Udo Schwingenschlögl, Klaus Viktor Peinemann Abstract Water vapor removal is a crucial process for several industries e.g., air conditioning systems, flue gas dehydration, compressed air dry...

Collisional Stability of Fermionic Feshbach Molecules verfasst von J. J. Zirbel, K. K. Ni, S. Ospelkaus, J. P. D Incao, C. E. Wieman, J. Ye, D. S. Jin Abstract Using a Feshbach resonance, we create ultracold fermionic molecules starting from a Bose Fermi atom gas mixture. The resulting mixture of atoms and weakly bound molecules provides a rich system for studying few body collisions because of the variety of atomic ...

Probing cluster structures with sensor molecules Methanol adsorbed onto gold clusters verfasst von R. Rousseau, G. Dietrich, S. Krückeberg, K. Lützenkirchen, D. Marx, L. Schweikhard, Clemens Walther Abstract Structural, dynamical and electronic properties of the adducts formed by adsorbing methanol onto size selected gold clusters are investigated using infrared multiple photon dissociation spectroscopy of trapped Au n CH 3 OH, n 15, ...
