- The electronic spectra of ArXe molecules in the 80 300-89 500 cm(-1) region were recorded by (2 + n) and (3 + n) REMPI methods. The vibrational progressions attributed to transitions of molecules from the ground state to the bounded excited state and wide unstructured bands related to transitions to the continuous upper state were obtained. The molecular constants of ArXe* were calculated for all the observed progressions in the 80 300-87 000 cm(-1) region as an approximation of an anharmonic oscillator and the Morse potential. For different excited states the energy of harmonic oscillator and the dissociation energy are changed from 10 to 100 cm(-1) and from 70 to 750 cm(-1), respectively.

- The excited electronic states of ArXe molecules in the region 77 000-80 200 cm(-1) were studied using the (2+1) and (3+1) resonance-enhanced multiphoton ionization methods. The use of different methods of multi-photon excitation and Ar+ ion registration allowed us to obtain some new data. Molecular constants were obtained for previously unknown excited states of molecules with the following dissociation limits: ArXe* -> (ArS0)-S-1+Xe*6p[5/2](3) with Omega = 2, 3 symmetry; (ArS0)-S-1+Xe*6p[3/2](2) with Omega = 1, 2 symmetry; (XeS1)-S-0 -> Xe*6s'[1/2](1)(0) with Omega = 0(+) symmetry.
