Dc slice imaging, crossed beam reaction of chlorine radical with butane

DC SLICE IMAGING, CROSSED BEAM REACTION OF CHLORINE RADICALWITH BUTANEbyTAREK ABDUL GHANIDecember 2012Advisor: Dr. Arthur SuitsMajor: ChemistryDegree: Master of ScienceWe present an investigation of the reaction dynamics of Cl radicals withbutane in crossed beams, were studied at two collision energies: ~ 6.5 and 9kcal/mol. Product were ionized using a 157 nm probe laser, and detection wasthrough a dc slice detection setup. The translational energy distributionintegrated over all scattering angles; look similar for both collision energies. Theangular distribution shows that at high collision energy the there is a sharpincrease in the forward scattering. At low collision energy there is morebackscattering. The results show that the different scattering angles give differenttranslational energy distribution. The forward scattered peaks at approximately85% of the collision energy, with a similar distribution for both collision energies.The sideways-scattered product shows the broader distribution that extends intohigher energy. The back-scattered product showed the broadest distribution anda higher fraction of total energy showing up in translational energy.
