WebIntroduction The NIST Quantitative Infrared Database currently consists of a collection of absorption coefficient spectra of volatile organic compounds. These spectra were measured from primary gas standards prepared and verified at NIST. Spectra are provided in 5 resolutions from 2.00 cm −1 to 0.125 cm −1 using 5 apodization functions. WebThe spectra of ethyl acetate and ethyl benzoate are shown below. Note that the C=O stretch of ethyl acetate (1752) is at a higher wavelength than that of the α, β-unsaturated ester ethyl benzoate (1726). Also note the C–O …
