Fig. 1.1.The structure of hydrogen atom. The hydrogen atom can be represented by the symbol H and a dot that stands for the single electron in the neutral atom. In its lowest energy form, the electron occupies the 1s orbital, spherically symmetrical around the hydrogen nucleus. In the secti...
Collision quenching of the metastable 2S state of muonic hydrogen and the muonic helium ion We present calculations of the cross section for quenching of the metastable 2S state of muonic hydrogen (μp) in collisions with a hydrogen atom, at colli... RO Mueller,VW Hughes,H Rosenthal,......
condition. Here, H-atom addition energy (HAE) was calculated via density functional theory (DFT) for these three candidates and used to assess their ability to carry a H atom. These HAE values were defined as the energy change for the addition of a H atom to a molecule (M) in gas ...
A high-level quantum chemistry investigation has been carried out for the abstraction by chlorine atom of hydrogen from methane and five monosubstituted methanes, chosen to reflect the chemical functionalities contained in amino acids and peptides. A modified W1′ procedure is used to calculate bench...
The V atom adsorbing the water molecule is defined as V-1, the V-2 corresponds to the one with the largest positive partial charge, while V-3 is at the minima. c The O-binding energies (EO–binding, green dots) of O to Vn+, and the zero-point-vibration corrected total energies of...
: an electrostatic attraction between a hydrogen atom in one polar molecule (as of water) and a small electronegative atom (as of oxygen, nitrogen, or fluorine) in usually another molecule of the same or a different polar substance hydrogen bonding noun ...
