Direct measurements of the lifetimes of polyatomic molecules vibrationally excited above the dissociation threshold in intersecting laser and molecule beams
Apatin V. P., Makarov G. N.
A method is proposed for measuring the lifetime of (CF3)3 CBr molecules which are "overexcited," i.e., excited above the dissociation threshold, by the pulse from a C02 laser. The molecules are in a beam intersected by the laser beam. The first results on the use of this method are reported. Information has been obtained on the dynamics of the excitation of levels above the dissociation threshold.
