The region of the IR spectrum between 1500 - 400 cm^-1 would be significantly different for the following two substances?

Question

Quizplus · Accepted Answer

The region of the IR spectrum between 1500 - 400 cm^-1 is known as the fingerprint region, where unique vibrations for each substance are observed. Therefore, if two substances have significantly different molecular structures, they would exhibit different vibrations in this region, leading to observable differences in their IR spectra.
