Development of Monoterpene Oxidation Mechanisms: Results from Laboratory and Smog Chamber Studies A contribution to subproject CMD L Ruppert, KH Becker, B Noziere and M. Spittler Bergische Universitdt - Gesamthochschule Wuppertal, Physikalische Chemie (FB 9), Gaufistrasse 20, D-42097 Wuppertal, Germany Introduction The atmospheric oxidation of biogenic VOCs and especially monoterpenes is still poorly represented in atmospheric chemistry models, if at all. Partly this is simply due to the fact that the mechanistic data base for the complex reactions of these compounds is only fragmentary. Whereas rate constants for the initiating reactions of the monoterpene oxidation with OH, NOg and 63 are available, only a few main products have been reported for most of these reactions (e.g. pinonaldehyde from oc-pinene). The carbon balance seldom exceeds 50 %. The progress reported here, concentrates on the following aspects: 1. Formation of o
