High-temperature measurements of acetylene VUV absorption cross sections and application to warm exoplanet atmospheres
Acetylene's VUV absorption cross sections grow with temperature, and using the 773 K measurements in a hot Jupiter model lowers the predicted C2H2 abundance by up to 40% near 5 x 10^-5 bar.
