Ab initio computations have been performed on aniline and N-methylaniline using standard STO-3G orbitals to analyze the inversion barrier and the degree of non planarity in the two molecules. Our analysis indicates that the lowering of thei barrier in N-methyl-aniline with respect to aniline is...
The harmonic force field of SiFCl was derived from the centrifugal distortion constants and the inertial defects determined for both isotopic species and was used to calculate the vibrational frequencies of the molecule. The average structure in the ground vibrational state was determined to be rz(...
Aniline is a closed chain molecule, it is not linear. What is the property of aniline? Aniline is an aromatic cyclic compound that is also weakly basic. The reason why it is weakly basic in spite of having -NH2 as a functional group (a basic group) is due to resonance. When the ...

The new (Z)-pyrazol β-keto-enol as model-molecule has been prepared in accepted high yield; the structure was investigated by X-ray single crystal diffraction (XRD) and Density Functional Theory (DFT) modeling. Several hydrogen bonds interactions were recorded experimentally via XRD and theoretica...
