Can someone help me to clear out a few questions about Intensity from spectral lines.
- I have seen in many reports the unit cm-2 atm-1? Where does this come from?
- What is the differences between line strength and the absolute intensity if the spectral line?
- If you measure light from for example a flame with a FTS (Fourier Transform Spectrometer) What unit does the recorded spectrum have? Is this not possible to determine and you simply use arbitrary units.
- Why is it difficult to measure absolute intensities?
