aThe oxygen atom of the water molecule is more electronegative than the hydrogen atom (i.e., it attracts more the electrons). As a result, the side of the molecule with the oxygen atom has a partial negative charge. A molecule with such a charge difference is called a dipole.[translate]...
For each n, the most stable structures are quite similar for different metal types, and the oxygen molecule prefers to be adsorbed onto M atoms. It is found that the activation degree of oxygen is higher on clusters with non-noble metal Cu than that of Ag or Au containing clusters, by ...
N-Terminated triangular BN (t-BN) cluster doping can reduce the energy barrier more effectively compared to a t-BN with a B edge or quadrangular BN cluster. Interestingly, the B atom neighboring the N edge, only in the case of N-terminated t-BN doping, is determined to be the most ...
The intense reactivity of ozone is sometimes explained by suggesting that one of the three oxygen atoms is in an “atomic” state; on reacting, this atom is dissociated from the O3molecule, leaving molecular oxygen. The molecular species, O2, is not especially reactive at normal (ambient) temp...

The ir spectrum of normal and isotopically substituted SiCl 3OH molecules is reported. The frequencies were fitted to a general valence force field.关键词: Experimental/ atom-molecule reactions infrared spectra of polyatomic inorganic molecules matrix isolation spectra oxygen ozone photolysis silicon ...
The split configuration is electrically neutral. At the octahedral site, the Oi acts as a deep double acceptor [4]. An O2 molecule can be adsorbed at the ZnO surface, where it dissociates into oxygen adatoms that enter the bulk as negatively charged Oi [54]. By studying the isotopic ...
A Look at the Interacting Molecule of Carbon Dioxide and Re-Emitted AsInfraredRadiation Now, the next question in mind would be how carbon dioxide can be an energy interacting molecule? This is because carbon dioxide reacts to photons coming from an atom or molecule which absorbs energy. ...
