Abstract

This work is devoted to investigation on the ultrafast dissociation phenomena of the cyclopentadienyl manganese tricarbonyl–CpMn(CO)3 molecule and its emerging fragments by means of mass spectrometry and pump–probe spectroscopy. Studies on the laser intensity and wavelength dependence observed in the recorded mass spectra are reported. Time-resolved mass spectra were measured in order to investigate the fragmentation time scale. From the recorded two-color pump and probe spectra the lifetimes of the electronically excited states for all CpMn(CO)n+ (1 ≤ n ≤ 3) ions were extracted. By employing laser pulses of ca. 40 fs, wave packet dynamics of the parent ion CpMn(CO)3+ as well as for the first fragment have been resolved. These findings have already been successfully exploited in optimal control experiments. The present studies are extended to different pump pulse intensities.
