One-electron bond

Japanese: 一電子結合 - イチデンシケツゴウ
One-electron bond
This refers to a chemical bond formed between two atomic nuclei A and B when one electron is shared by both nuclei A and B. The dissociation energy of a one-electron bond is smaller than the dissociation energy of a normal covalent bond formed when two electrons pair up. A typical example of a one-electron bond is the hydrogen molecule ion H2 + , whose dissociation energy is 2.55 x 105 J/mol, which is about 60% of the dissociation energy of the hydrogen molecule H2, which is 4.27 x 105 J/mol.

Japanese:
1個の電子が2個の原子核A,Bによって共有されることによってAB間に生じる化学結合を指す。一電子結合の解離エネルギーは,2個の電子が対をなすことによって形成される通常の共有結合の解離エネルギーよりも小さい。一電子結合の代表例は水素分子イオンH2にみられ,その解離エネルギーは水素分子H2の解離エネルギー4.27×105J/molの約60%にあたる2.55×105J/molである。【田隅 三生】
