WebThe short answer is that Gaussian uses a coordinate system where the normalized cartesian displacement is one unit. This differs from the coordinate system used in most texts, where a unit step of one is used for the change in interatomic distance (in a diatomic). The vibrational analysis of polyatomics in Gaussian is not different from that ...

Web11 de abr. de 2024 · Our research group has made incursions into the scarcely known coordination chemistry of rhenium(II). The literature shows that Re(II) mononuclear complexes are attractive in molecular magnetism due to high magnetic anisotropy because of a significant spin-orbit coupling, making them a potential source for new molecule … WebA new normal coordinate analysis of CF3 CH, has therefore been carried out. Since it is desirable to have as many spectral data as possible for the calculation of force constants, it was decided to make a combined normal coordinate analysis of CF3CH3 and its deuterated isomer, CF3-CD3. The infrared and Raman data for CF3---CH3 were those ...
