Helium hydride molecule
The helium hydrogen ion is isoelectronic with molecular hydrogen (H 2). Unlike the dihydrogen ion H 2, the helium hydride ion has a permanent dipole moment, which makes its spectroscopic characterization easier. The calculated dipole moment of HeH is 2.26 or 2.84 D. The electron density in the ion is higher … Meer weergeven The helium hydride ion or hydridohelium(1+) ion or helonium is a cation (positively charged ion) with chemical formula HeH . It consists of a helium atom bonded to a hydrogen atom, with one electron removed. … Meer weergeven From decay of tritium The helium hydride ion is formed during the decay of tritium in the molecule HT or tritium molecule T2. Although excited by the recoil from the beta decay, the molecule remains bound together.
