Abstract
Optical extinction measurements of acetylene smoke in a 1.8-m tube at wavelengths of 0.5145 and 10.6 μm give specific extinction coefficients AE of 9.8 ± 0.8 and 0.94 ± 0.1 m2 g−1 respectively. The Mie theory applied to unagglomerated small carbon spheres can simulate the optical properties of acetylene smoke in the visible region but underestimates the specific extinction at 10.6 μm by at least a factor of 2. Both the visible and infrared experimental data are consistent with a model in which agglomeration of the smoke particles enhances the infrared extinction over that from small individual spheres.

The elements of the Mueller matrix for polydisperse systems of irregular, randomly oriented particles have been measured in absolute terms as a function of scattering angle for two wavelengths and compared to the matrix elements that were calculated for assemblies of spherical particles that fit the same particle size distribution function and have the same (real) refractive index.

The opacity of a black smoke (an aerosol of carbon spheres) is calculated from the Mie theory for several lognormal particle distributions to show how the opacity can vary by a factor of 2 or more as the size distribution is varied.
