Structure and stability of the HFF and FHF radicals
1977年8月1日 · Both complexes can be essentially described by an HP dipole (exhibiting a standard HF bond length) attracting a fluorine atom, with an FF distance of 5.14 bohr calculated for the HF F ground state and an H F bond of 4.3 bohr for the most stable FHF species.
Anticooperativity of FHF hydrogen bonds in clusters of the type F
2016年2月5日 · Mutual influence of hydrogen bonds in the molecular clusters. Anticooperative effects in energy and structure for F − × (HF) n and RF × (HF) n complexes. The addition of each subsequent HF ligand leads to a decrease in the binding energy. The geometric parameters are less sensitive to the mutual influence than the energy changes.
NMR Chemical Shift of a Helium Atom as a Probe for Electronic Structure ...
In this work, we present the first results of outer electronic shell visualization by using a 3 He atom as a probe particle. As model objects we have chosen F –, FH, and FH 2+ species, as well as the hydrogen-bonded complex FH···F – at various H···F – distances (3.0, 2.5, 2.0, and 1.5 Å and equilibrium at ca. 1.14 Å).
Material Balances XIII — Kinetics and Reaction Engineering
So, we’ve got 4 differential equations that tell us how 4 dependent variables (F B, F D, F H, F T) change as a function of the one independent variable, V. We can solve this system if we can define everything on the right hand sides of the above equations (R B, R D, R H, and R T) in terms of F B, F D, F H, F T, and/or V. We know how to do this!!
FBF-X - MTE
The FBF-X series brings together all the benefits of the travelling column range in a single machine with an even more robust design. In combination with size 100 guideways, the most demanding jobs are made possible and new machining heights can be reached.
Bonding in FHF−, (HF)2, and FHF - Davidson - Wiley Online Library
2004年3月12日 · Bonding in FHF −, (HF) 2, and FHF is compared from the molecular orbital and electrostatic bonding viewpoint. The electrostatic force is dominant in the formation of FHF − and HF dimer. Exchange repulsion dominates in preventing the formation of FHF and leads to a D∞h transition state for H exchange.
