Single-photon threshold photoionization has been used to explore the ionization dynamics of the NH+3 (X 2A2″)←NH3 (X 1A1) transition which involves a pyramidal-to-planar geometry change. Rotationally resolved threshold photoelectron spectra are presented for four vibrational levels of the X 2A2...
This review delves into the potential applications of lead-free organic–inorganic perovskite-type crystals, specifically [NH3(CH2)nNH3]MCl4(n = 2, 3, 4, 5, and 6;M = Mn, Co, Cu, Zn, and Cd). We seek organic–inorganic hybrid perovskite materials characterized by high or no...
Geometries and Interaction Energy of Complexes Figure 2 shows the optimized structures of the 6-OTX3-fulvene···NH3 complexes (T = C, Si, and Ge; X = H and F). In most complexes except 6-OCF3-fulvene···NH3, the angle ∠O–T···N was close to 180◦, and three T–X ...
TS2 appeared to be closer to the reactants' geometry; therefore, Reaction (2) traversing via TS2 was more exothermic (∆rxn, 0KH◦ = −9.4 kcal/mol vs. −6.4 kcal/mol). For both the transition states, the bond angle (δC. . .H. . ..N) was almost collinear (see Figure...
Figure3is the high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) images of Al-SBA-15 MMS, which evidences that the resulting Al-SBA-15 MMS had a perfect hexagonal porous structure (Fig.3a). And Al species are uniformly distributed on the molecular sieve, both...
The dissolution behavior of NH3in conventional ILs was firstly reported in 2007, and it was inferred that strong intermolecular complexes between NH3and ILs are formed [32]. Subsequently, it was found that cations had a greater influence on NH3solubility than anions and that the hydrogen bond bet...
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±...
CO adsorbs atop Ni surface atoms through the C atom in an essentially perpendicular geometry (tilt angle 12±12°) with a C–Ni nearest-neighbour distance of 2.07±0.02 A˚. NH3 also adsorbs atop Ni surface atoms with a N–Ni distance of 2.06±0.02 A˚. These bondlengths are only ...

Combining the findings described in Section 2.5.1 and Section 2.5.2, one can have a different view angle of the cluster size effect. For the unsupported cases, with using the SM as the energetic reference, the stability of either IM1 or IM2 increases with the order of Ru1 < Ru2 < Ru...
