Go To: Top, IR Spectrum, References Data from NIST Standard Reference Database 69: NIST Chemistry WebBook The National Institute of Standards and Technology (NIST) uses its best efforts to deliver a high quality copy of the Database and to verify that the data contained therein have been selected on the basis of sound scientific judgment. The two strong bands arise from the symmetric and antisymmetric #"C-O"# stretches of the ester #"COO"# group, and the weaker band is the ether #"CO"# stretch of the #"OCH"_3# group.
