WebAug 26, 2010 · The original EPA-IR collection contained 3,300 spectra measured by GC-IR under EPA contract. These were obtained at 4 cm-1 resolution from 450 to 4000 cm-1, although values below 500 cm-1 and above 3900 cm-1 often show extraneous signals. … WebFig. 1 Gas-phase infrared spectra, collision cross sections and structures of FA 18:1 double bond isomers derivatized with 3-pyridylcarbinol. (a) The double bond position and configuration influence the frequency of the carbonyl stretching vibration and the diagnostic fingerprint region (1050–1250 cm −1). (b) The carbonyl stretching frequencies correlate …
