A possible interpretation of the infrared spectrum of methoxyethane

I was unable to find an image of the infrared spectrum of methoxyethane, but considering the infrared spectra of methoxymethane and ethoxyethane and data tables, you can make some reasonable predictions as to the most prominent absorption wavenumbers for methoxyethane.

The expected most prominent infrared absorption lines of methoxyethane

In general for ethers, the C-H stretching vibration absorption bands are found in the 2800 to 3000 cm-1  wavenumber region - typical 'alkyl values'.

More specifically, the C-H stretching vibrations for a O-CH3 group occur at wavenumbers 2830 to 2815 cm-1.

In general, a group of C-O stretching absorptions, from the ether linkage (C-O-C), are found around wavenumbers 1150 to 1060 cm-1.

more specifically, the C-O stretching vibrations for a O-CH3 group occur at wavenumbers ~1250 cm-1.

The absence of other specific functional group bands will show that particular functional group is absent from the methoxyethane molecular structure.
