| Abstract: | Data on excited states of XeKr molecules in the energy range 78280–77600 cm?1 are obtained. Using the method of multiphoton laser photoionization of molecules in a supersonic jet, five vibrational progressions of XeKr molecules are obtained, which are attributed to five electronic-vibrational transitions from the ground state of the XeKr molecule of the symmetry 0+ to excited states of the symmetry Ω = 0+, 1, 2 with the dissociation limit Kr1 S 0 + Xe*6p[5/2]2 and of the symmetry Ω = 1, 2 with the dissociation limit Kr + Xe*6 p [5/2]3. The molecular constants of the corresponding excited states of the XeKr molecule are estimated. |
