This is an introductory survey of the vibrational spectroscopy of defects in semiconductors that contain light-mass elements. The capabilities of vibrational spectroscopy for the identification of defects, the determination of their microscopic structures, and their dynamics are illustrated by a few examples. Several additional examples are discussed, with a focus on defects with properties not obviously accessible by vibrational spectroscopy, such as the diffusivity of an impurity, the negative U ordering of electronic levels, and the time constant for a nuclear-spin flip. These novel properties have, nonetheless, been revealed by vibrational spectra and their interpretation by theory. Published by AIP Publishing.
