✦ Synopsis

The emission and direct excitation spectra of XeH (D) and Xe,H(D) were observed after photolysis of HZ (D2) in an argon matrix doped with xenon and hydrogen (deuterium). The emission bands are typical bound free transitions whereas the excitation spectra show pronounced vibrational progressions. With the help of the isotope effect (hydrogen and deuterium) it was possible to determine the vibrational frequencies w, and the term values T,of the XeH( D) and Xe2H(D) potential curves. These parameters are compared with the corresponding values of KrXeH(D) in a krypton matrix. The great similarities between the various excitation spectra are explained by a simple model
