Spectral broadening

  1. Jun 1, 2008 #1
    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
    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).
