The molecular geometry of the complex of gallium trichloride with ammonia, Cl 3Ga.NH 3, has been studied by electron diffraction. The most important internuclear distances in terms of r a parameters are as follows: r(Ga-Cl) = 2.142±0.005, r(Ga-N) = 2.057±0.011, r(ClCl) = 3.642±...

The observed results for N(CH3)3 are contrary to predictions based on commonly used intuitive arguments involving lone pairs, molecular geometry and hybridized orbitals. The present work is supportive of the view that CH3 groups are intrinsically more electron attracting than H when bonded to N.A...

Collision strengths for electron-impact excitation of nitrogen-like Fe ions (Fe19+) have been calculated within the semi-relativistic R-matrix Breit-Pauli approximation. Twenty-three fine-structure levels arising from the 12 2s(2)2p(3), ... ML Bm.,K Kp. - 《Journal of Physics B Atomic ...
This CL microscope tightly integrates a high numerical aperture (NA 0.72) achromatic reflective lens within the objective lens of a field emission gun scanning electron microscope (FEG-SEM). The focal plane of the light lens matches the FEG-SEM optimum working distance. The CL collection ...
For each geometry, an all-electron single point calculation was performed using PBE exchange–correlation functional [50] implemented in ADF software [51, 52]. A large QZ4P basis set was employed for all atoms in the Z[CuI(NH3)] model and for Cu and its 30 nearest neighbors in the [...
