Characterization of two-photon LIF detection of CO
Settersten, Tom

Carbon monoxide is an important component of reacting flows such as plasmas and flames, and its detection is significant in numerous research fields including planetary atmospheric physics, biochemistry, surface science, and combustion. Laser-induced fluorescence (LIF) detection of CO by two-photon excitation of the Hopfield-Birge electronic transition (X1S+ B 1S+)and collection of the blue-to-green emission in the Angstrˆmbands (B1S+A1) was first demonstrated by Loge, et al.1,2 This technique has received considerable attention for applications in combustion. As we continue to develop our ability to quantitatively model two-photon LIF of CO, it becomes important to include detailed submodels for quenching pocesses and the photolytic background caused by photolysis of vibrationally excited CO2 (see linksbelow).
