Question

Can someone please help me analyze this IR spectra and help me put it in the correct IR notation

Here is the spectra example

Thanks so much for the help!

055 44 3015.73 1972 18 1675.74 159。78 315 934 辽

Answer 1

First thing frst, IR should have been recorded as a plot between Transmitance and wavenumber but has been recordes as Absorbance v/s wavenumber. Both are interconvertible that is not a problem,

Follwing information can be had using the given IR spectrum,

peak around 3015 and 3055 cm-1 could be due alphaitic -CH absorbtion.Since, there is no prominent peak between 1600 and 1800 cm-1 which rules out the presence of any carbonyl functional group in the Ir spectrum

Futher peak around 1100 cm-1 could be due C-O absorption,
