Mass spectrometry and infrared spectroscopy are complementary techniques because mass spectrometry provides information about the molar mass and formula while infrared spectroscopy helps identify the functional groups in the formula.

Question

Quizplus · Accepted Answer

Mass spectrometry gives detailed information about the molecular weight and structure of a molecule, allowing for the determination of its molecular formula. Infrared spectroscopy, on the other hand, identifies specific functional groups based on their characteristic absorption of infrared light, thus providing information about the molecule's chemical structure. Together, these techniques offer a comprehensive view of a molecule's composition and structure.
