Molecular spectra have a complex structure. Typical molecular spectra are band spectra, which are observed in emission, absorption, and Raman scattering in the form of the aggregate of more or less narrow bands.

As a result the study of molecular spectra has become one of the most important means for investigating molecular structure. This first volume deals with the spectra of diatomic molecules and the conclusions that can be drawn from them concerning the structure of these molecules.
