Peak Shape: Pseudo Voigt
where .
The function is a linear combination of a Lorentzian
(L)and a Gaussian (G) of the same FWHM (H), so there are two parameters
characterising the peak shape:
.
If
and
are normalised,
is also normalised. The integral breadth of a normalised pseudo-Voigt
function is just the inverse of the maximum value. The FWHM is the same for L(x), G(x) and pV(x).
