Abstract

Optoacoustic measurements of acetylene smoke in a simple nonresonant cell at wavelengths of 0.5145 and 10.6 µm give specific absorption coefficients A A of 8.3±0.9 and 0.76±0.1 m2 g-1, respectively. In the visible region, about 85% of the total optical attenuation is due to absorption. These data are consistent with a simple model in which the smoke is comprised of agglomerated carbon spheres. The experimentally determined responsivity of the optoacoustic cell is in good agreement with theory.
