The authors have presented a comprehensive discussion of the status and possibilities of experimental spectroscopy as it exists today. This includes applications in the fields of physics, chemistry and biology. Emission spectroscopy is treated in detail, including discussions of equipment, facilities and technics. Several methods, such as fractional distillation and the moving plate method especially applicable to the examination of biologic mixtures, are discussed. Absorption spectrophotometry in the ultraviolet, visible and infra-red regions is discussed in less detail. However, these sections constitute one of the best presentations on this field available today in book form. Currently, there is a great increase in the use of spectrophotometry in clinics and pharmacology laboratories. The chapters relating to this subject are recommended reading for all connected with such laboratories.
In discussing a field so widespread as spectroscopy, it is impossible to present an exhaustive description of each technic. An extensive bibliography is given,
