The dynamics of the depletion of separate vibrational-rotational states with IR multiphoton excitation of molecules, cooled in a pulsed jet, are studied for the first time with the help of a frequency-tunable diode laser. The fraction of molecules excited by the laser pulse from separate rotational sublevels is measured and its dependence on the excitation conditions is studied.
