摘要：

Infrared emission from carbon dioxide produced in the 193 nm photolysis of pyruvic acid vapor has been investigated using time-resolved Fourier transform infrared spectroscopy as a probe. A broad feature, strongly red-shifted from the antisymmetric stretching fundamental (v3) of CO2, dominates the early spectrum. A statistical model using a linear surprisal is shown to provide good agreement with the observed spectral contour, but only if the energy available to the photofragments corresponds to the direct formation of acetaldehyde along with CO2.
