Atmospheric Pressure Acetylene Detection by UV Photo-Fragmentation and Induced C-2 Emission
Författare
Summary, in English
Detection of C2H2 via UV photo-fragmentation, followed by monitoring the C(2)d(3)Pi(g)-a(3)Pi(u) fluorescence, is explored at atmospheric pressure and at temperatures of 295 K, 600 K, and 800 K, for excitation wavelengths 210 to 240 am using a broadband laser source (similar to 3 cm(-1) fwhm). At the lower temperature, C-2 emissions correlate closely with C2H2 (A) over tilde <- X absorption bands, and the excitation spectra suggest a higher-transition probability for the v(4)'' = 2 and 3 states than for the v(4)'' = 0 and 1 states. As temperature increases, the excitation spectra exhibit a higher nonresonant background.
