Publikováno v: Vibrational Spectroscopy. 24:75-92

In recent years, considerable developments have taken place in Raman, mid-infrared (mid-IR) and near-infrared (NIR) instrumentation. This has had a major influence on the number and type of applications these techniques have in industry. In the curre

Structure of Ammonia Trimethylalane (Me3Al-NH3): Microwave Spectroscopy, X-ray Powder Diffraction, and ab Initio Calculations

Autor: Uwe Ruschewitz, Oliver Indris, Wolfgang Stahl, Jens Müller, and Holger Hartwig

Publikováno v: Journal of the American Chemical Society. 121:4647-4652

The structural parameters of the ground-state geometry of Me3Al-NH3 calculated by various ab initio methods (HF, B3LYP, and MP2) are presented. For the two isotopomers Me3Al-14NH3 and Me3Al-15NH3, the rotational transitions J = 1 ← 0 and J = 2 ←

Analysis of Internal Rotation and Determination of the Heavy Atom Structure of anti-2,3-Dimethylthiirane by Fourier Transform Microwave Spectroscopy

Autor: Helmut Dreizler, Holger Hartwig

Publikováno v: Zeitschrift für Naturforschung A. 51:1099-1106

We used the advanced technique of Fourier transform microwave spectroscopy to measure and assign the ground state rotational spectrum of anti-2,3-dimethylthiirane, and to analyse the internal rotation of the two methyl groups. The potential parameter

The Rotational Spectrum of 2,2-Dimethyloxirane

Autor: Holger Hartwig, Helmut Dreizler

Publikováno v: Zeitschrift für Naturforschung A. 47:1063-1066

The microwave spectrum of 2,2-dimethyloxirane (isobutylene oxide) in the ground and torsionally excited states was assigned and analyzed. The potential barriers hindering the internal rotation described by V3 = 11.312(9) kJ/mol and V’1 2 = 1.059(32

A Contribution to the Microwave Spectra of eis- and trans-2,3-Dimethyloxirane by Fourier Transform Spectroscopy

Autor: Holger Hartwig, Helmut Dreizler

Publikováno v: Zeitschrift für Naturforschung A. 47:1051-1057

Microwave Fourier transform spectroscopy was used to reinvestigate the rotational spectra of cisand trans-2,3-dimethyloxirane. The potential barriers hindering the internal rotation, internal rotation parameters, and partial rs-structures were determ
