✦ Synopsis

A simple uniform-pressure diffusion apparatus has been used to measure the diffusivities of the gaseous fluorocarbons CF4 and CF2C12 in air at atmospheric pressure and room temperature (293 K). The diffusion coefficients arc found to be D(CF4-air) = 0.121 cm2s-r and D(CFaCla-air) = 0.098 cm2s-*. The observed diffusion flux ratios arc in agreement with Graham's diffusion law.

Splitting of the monomer bands was also observed; it is attributed to cis-trans-isomerism; the band of shorter wavelength is assigned to the all-trans-form, that of longer wavelength to a mono-cis-isomer that arises by rotation around the C-2/C-8 bond

The blowout limit of a circular jet diffusion flame in a low velocity coflowing stream of air is extended significantly by the introduction of a small amount of some fuel vapor in a surrounding flow. The jet fuels employed were methane or hydrogen, while the coflowing stream contained, in turn, meth
