  • Velocity Map Ion Imaging of Chlorine Azide Photolysis: Evidence for Photolytic † Production of Cyclic-N3
    Velocity Map Ion Imaging of Chlorine Azide Photolysis: Evidence for Photolytic † Production of Cyclic-N3 N. Hansen and A. M. Wodtke* Department of Chemistry and Biochemistry, UniVersity of California at Santa Barbara, Santa Barbara, California 93106 ReceiVed: March 13, 2003 The method of velocity map imaging was applied to study the photodissociation dynamics of ClN3 near 235 2 nm under collision-free conditions. Derived kinetic energy distributions of state-selected Cl ( PJ) provide a medium-resolution energy spectrum of the N3 fragment. Markedly bimodal distributions are observed that 2 suggest simultaneous formation of the linear-N3 (X˜ Π) isomer as well as an energetic form of N3, consistent with recent theoretical predictions of a cyclic isomer, resembling an isosceles triangle. Angular distributions of the photofragments indicate that 21A′ r 11A′ excitation is the most important pathway to photoproducts. 2 Branching ratio measurements between the dominant spin-orbit excited-state Cl* ( P1/2) and the spin-orbit 2 ground-state Cl ( P3/2) showed Cl*/Cl ≈ 0.8/0.2.
