Abstract
The function of the prism or grating within the monochromator unit of the spectrophotometer has been considered in the section devoted to instruments. Attention was drawn to the unequal dispersion of different prism materials with changing frequency; improvements in spectral resolution may therefore be obtained by correct selection of the prism. Table 6 gives the useful infra-red frequency ranges for several types of prism, but it is towards the lower frequencies in the quoted ranges that the prism material is most efficient.
