From: Photo-tautomerization of acetaldehyde as a photochemical source of formic acid in the troposphere
Fourier transform infrared spectra of the photolysis products. a Infrared spectrum (black) following 7 min of 315 nm irradiation of a mixture of 10 Torr acetaldehyde in 750 Torr nitrogen. The remaining acetaldehyde has been subtracted from the spectrum. The inverted blue trace shows the sum of scaled reference spectra of photochemical products. The red trace is an infrared reference spectrum of vinyl alcohol, a portion of which, between 1550 and 1700 cm–1, is expanded in the inset b
