 Title    Kinetics of the Reaction HOCO + 0 2 in the Gas Phase  
 Abstract    Using the discharge flow method, the kinetics of the gas phase reaction HOCO + 0 2 products (1) was investigated at room temperature and pressures around p « 2.0 mbar with Far Infrared Laser Magnetic Resonance (FIR-LMR) detection of HOCO, H0 2 , and OH. From the measured concen-tration-versus-time decay profiles of HOCO in the absence and presence of a large excess of 0 2 , the overall rate constant of the reaction was found to be k, (296 K) = (9.9 ±1.5) • 10 11 cm 3 /mol • s. The main reaction channel, which leads to production of H0 2 + C0 2 , could be established.

 Title    Magnetischer Circular Dichroismus (MCD) von cyclischen rc-Elektronensystemen mit 4N±1 Elektronen  
 Abstract    The theory of the magnetic circular dichroism (MCD) of cyclic re-electron systems with 4 N ± 1 electrons, such as the radical anion of [16] annulene, has been investigated in the perimeter model approximation. General solutions and formulas for the calculation of the Faraday parameters A, B, and C are derived analytically. The calculated and measured spectra of the 17 re-electron [16] annulene radical are in good agreement.
