We describe the preparation of diatomic trications using intense femtosecond laser pulses, and discuss the feasibility of using femtoseond pump-probe techniques to measure the vibrational spectrum of Cl\u2082\ub3\u207a . Initial attempts to observe the vibrational spectra of Cl\u2082\ub3\u207a were unsuccessful. Possible refinements to the experiment are guided by calculations of the electronic states, transition moments, and field-dressed potential curves for Cl\u2082\ub3\u207a . Solution of the time-dependent Schr\uf6dinger equation using these theoretical data as input allow an accurate simulation of pump-probe experiments and their time-delay signals. Optimization of the experimental parameters via the simulation suggests an improved approach to obtaining the spectra of trications, with special emphasis on the unusual aspects of these systems.Peer reviewed: YesNRC publication: Ye
