Question

Quizplus · Accepted Answer

Mass spectrometry measures the mass-to-charge ratio of ions present in a sample, allowing for the determination of the molar mass and formula of the compound. In contrast, infrared spectroscopy measures the absorption of infrared radiation by the functional groups present in the compound. Therefore, mass spectrometry provides information about the overall mass and formula of the compound, while infrared spectroscopy helps identify the specific functional groups present. Together, these techniques can provide a more complete understanding of the composition of a sample.
