Kinetic energy time-of-flight (KETOF) mass spectroscopy in combination
with femtosecond pump-probe and molecular beam techniques is used to map
molecular dynamics along an internuclear coordinate. By recording transient
KETOF mass spectra we monitor the vibrational wave-packet motion on a neutral
electronic state for all possible internuclear distances simultaneously. The power of
this method is demonstrated by the one dimensional wave-packet motion on the 
double minimum state of the sodium dimer. For
comparison with the experiment quantum mechanical simulations were performed.
