COMMENTS: Absorption measurements in shock-heated 3-pentanone-argon diluted mixtures at temperatures above 300 and up to 1100 K

At each temperature, the absorption cross sections between 230 and 330 nm can be approximated by a Gaussian function

σ(λ, T) = A(T) exp {-[(λ-λc(T))/w(T)]2 with

A(T) (10-20 cm2 molecule-1) = 4.77+ 0.00487 T(K) (maximum),
λc(T)(nm) = 273.7 + 0.0186 T(K) (center of the Gaussian profile),
w(T) (nm) = 25.1 + 0.0101 T(K) (characteristic width).

The absorption cross section data were obtained by personal communication from Jon D. Koch (August 2008)
