The definition and uses of band width and band shape were introduced in Chapter 1, Section IIE, and were illustrated briefly. However, full use of these two characteristics requires a much more extensive acquaintance with actual spectra. It is necessary to have a mental picture of the appearance of the various kinds of multiplets under different ratios of J/∆,and it is desirable to have a picture of the overall appearance of the subspectra of various common structural groups. Such mental pictures lead to instant recognition of many structural features and save a great deal of time in interpreting spectra.
