Abstract

This chapter discusses mass spectrometry, infrared (IR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. The basic function of a mass spectrometer is to measure the mass of a molecule or, more correctly, an ion. A mass spectrometer can only separate and detect charged ions; neutral molecules cannot be detected. Both positive and negative ions can be detected, depending on the technique used. In IR spectroscopy, IR radiation is shone through a sample and certain frequencies (energies) are absorbed as molecules move to higher vibrational energy levels. Meanwhile, NMR looks at the environments of nuclei within molecules and is able to detect which nuclei are close to one another on the bonding network.
