Abstract
Photodissociation of 1,3-trimethylene oxide at 157 nm have been investigated using photofragment translational spectroscopy (PTS) technique. This experiment has been done by used newly built crossed molecular beam apparatus in the end station of U9 white light beamline at Synchrotron Radiation Research Center. At 157 nm excitation, the experimental results show that it only has one main channel : The translation energy distribution for this channel is broad and the cutoff is at 160 kcal / mol. By tuning the photon energy, we can check the cracking pattern for the reaction channel. The translational energy distribution is broad and it seems have four peaks.
