The detection of the 18.7 micrometer /SIII/ line in M42
The importance of forbidden line radiation is considered, taking into account lines in the visible and the infrared range. The result of a theoretical study conducted by Petrosian (1970) is shown in a graph which indicates the intensities of the IR lines predicted for M42. The predicted values were found later to be one order of magnitude too high
