Detection of TiH2 molecule in the interstellar medium is less probable
Abstract
Identification of TiH1 and TiO2 has been historical, as the Titanium was first time discovered in the interstellar medium (ISM). After finding TiO23, there is an obvious question about the search of titanium dihydride (TiH2). The existence of TiH2 in the ISM is quite probable, as the atomic abundance of hydrogen is about 1900 times larger than that of oxygen. We have discussed that the detection of TiH2 in the ISM is less probable, though it has a large electric dipole moment.
