Abstract

The IR emission spectra of a number of organic compounds have been examined in comparison with absorption spectra. The behavior of band intensity as a function of some experimental parameters has been considered in order to find the optimum range of the parameters for the recording of the emission spectra. It is shown that the spectra recorded on samples with low optical thickness and low crystal size are very close to absorption spectra. Specific fields of application can be found where emission techniques exhibit some advantages in comparison with absorption ones.
