The gas-phase electron diffraction determination of molecular structure is based on the phenomenon that a beam of fast electrons is scattered by the potential f rom the charge distribution in the molecule. The resulting interference pattern depends on the mol茅cula^geometry and intramolecular motion....

The electronic structure of Pd3 and Pt3 clusters and the detailed reaction mechanism of activation of H2 and CH4 on these clusters have been studied with a density functional method. Full geometry optimization has been carried out and led to the reaction mechanisms that are dramatically different...
The distortions from the tetrahedral geometry induced by linking two adamantane units are discussed. The potential barrier of 19.3 kJ mol−1 for internal rotation of two adamantyl cages around the central bond was determined by calculations of heat of formation for fully relaxed structures at ...
(3)Å3,dx=1.4214g cm−3,Z=2, λ (MoKα)=0l71069Å, μ=1.127cm−1,F(000)=356,T291K. The structure has been solved by direct methods and refined toR-0.058 for 1831 observed reflections. The presence of a highly asymmetric hydrogen bond influences the geometry of the phthalazine...
relatively weak interactions, which would potentially cause the1H chemical shift of DME to a higher value (H(DME)as the H bond donor instead), the dominant force is the H bond between H(TTE)and O(DME)and the resulting1H chemical shift of DME is toward a lower value. Further geometry op...
The crystalline structure and molecular mobility of poly(vinylidene fluoride) (PVDF) blended with poly(methyl methacrylate) (PMMA) have been investigated using solid-state 19F magic angle spinning (MAS) NMR spectroscopy. The origin of the characteristic crystalline peaks observed for three typical polym...
Describe the molecular geometry around each carbon atom in CH2CHCH3 using VSEPR theory. 1. What general principal is used in VSEPR theory to determine the shape of the electron cloud of a molecule? 2. Using the VSEPR theory, predict the molecular...
