This work investigates the possibilities of ground-state chemistry
by exciting molecular vibrations with femtosecond pulses in the
mid-infrared. Vibrational ladder-climbing to high excitation levels
(v=7-8) provides the necessary energy for bond scission. This
excitation scheme was demonstrated with metal carbonyls and
diazomethane. Only ultrashort laser pulses allow for excitation and
subsequent reaction on a time scale faster than the statistical
energy redistribution (IVR).
