The photoacoustic technique has been used in conjunction with an optical transmission measurement to determine the fraction of light absorbed in cigarette and acetylene smoke aerosols. At 0.5145-μm wavelength, the absorption-to-extinction fraction is 0.01 ± 0.003 for cigarette smoke and is in excellent agreement with predictions from Mie theory for smoke particles having a refractive index of 1.45–0.00133i and a median diameter in the 0.15–0.65-μm range. For acetylene smoke the absorbed fraction was 0.85 ± 0.05.
