Abstract
The gaseous refractive index of acetaldehyde in relation to the density of the substance is found to be 1·0007879 for λ 5461, while the dispersion over the range λ4358-λ6708 is represented by the Sellmeier expression (μ-1) d =7·4653×1027/(9779·3×1027-ν 2), νbeing the frequency of the incident light. The gaseous refractive indices of ethyl acetate for γ 5461 and γ 5893 (N.T.P. conditions) are found to be 1·001408 and 1·001399 respectively, both results being in agreement with previous work of Mascart.Keywords
