✦ Synopsis


The absorption coefhcient of nitrogen trifluoride at 147 nm was determined using two Pyrex cells in series. Measurement of the saturation ion current in trimethylamine, induced by the absorption of photons transmitted through the LiF window separating the photoionization and photolysis cells, provides an easy and accurate measurement of the fraction of light absorbed by nitrogen trifluoride in the photolysis cell (R. L. Lilly, R. E. Rebbert and P. J. Ausloos, J; Photo&em., 2 (1973/1974) 49).

The absorption coefficient of nitrogen trifhroride was found to be k=136*3 (atm at 298 K)-r cm-r (base e).
