We describe the preparation of diatomic locations using intense femtosecond laser pulses, and discuss the feasibility of using femtoseond pump-probe techniques to measure the vibrational spectrum of Cl2 3+. Initial attempts to observe the vibrational spectra of Cl2 3+ were unsuccessful. Possible refinements to the experiment are guided by calculations of the electronic states, transition moments, and field-dressed potential curves for Cl2 3+ . Solution of the time-dependent Schrödinger 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 locations, with special emphasis on the unusual aspects of these systems.
