Spectral broadening

I am predominantly a chemist researching electron energy loss spectroscopy, though have recently expressed some interest in spectral modelling. An area that perplexes me somewhat is applying broadening to a spectrum . For example, if I calculate a spectrum such that:

Energy Intensity
0 x
1 y
2
3 ...
4 ...


How can I apply for example a Lorentzian broadening factor to this? Any help would be most welcome.

You do a convolution of the actual spectrum (i.e. the data) with the broadening spectrum (your Lorentzian).
