AB  - As a continuation of the preceding paper in this issue (J. Phys. Chem. A 2005, 
      109, 6805), we studied photodissociation dynamics of the acetone S2 (n, 3s) 
      Rydberg state excited at 195 nm using femtosecond time-resolved photofragment 
      translational spectroscopy. The technique, which is implemented by the 
      combination of fs pump-probe ionization spectroscopy and kinetic energy resolved 
      time-of-flight mass spectrometry (KETOF), measured temporal evolutions of the 
      product kinetic energy distributions (KEDs) with a time resolution limited only 
      by the laser pulse widths. Two methyl product KED components were resolved and 
      assigned to the primary and secondary methyl products on the basis of their 
      temporal behaviors. The results support the mechanism in which the primary 
      dissociation occurs on the acetone S1 surface and provide complementary dynamical 
      information to that discussed in the preceding paper.
