Question: Where is the proof for this?

## General

This could be much clearer ... the intention here is to elucidate not obscure!
Is the symbol for the FWHM $\Gamma$? (Elvenlord Elrond) what the hell you are taken about —Preceding unsigned comment added by 69.70.15.250 (talk) 02:16, 15 September 2008 (UTC)

## Examples

Should we have some examples of the FWHM for different peak functions? (Elvenlord Elrond)

I think that special examples of FWHM are important, but only if they tend to occur often. The Normal distribution has the funny property that many real world examples can be modeled by it well. However, I would try to avoid making too many examples - that is something for another website 64.111.68.194 19:21, 29 December 2006 (UTC)

I think that the FWHM for a gaussian function should be rounded to 2.355σ, not 2.354σ. Same with the following part, 2.634 Skwoy 17:04, 5 July 2007 (UTC)skwoy

## Halfwidth, or half-width

In NMR there is a concept of half-width of the signal. Does this half-width (or halfwidth) correspond to FWHM? Kazkaskazkasako (talk) 09:15, 21 August 2009 (UTC)

FWHM = 2 * HWHM Kazkaskazkasako (talk) 17:18, 22 July 2013 (UTC)

Is the term "half-width" ambiguous? Could it mean the full-width at half maximum, or the half-width at half maximum? — Preceding unsigned comment added by 129.215.138.131 (talk) 10:42, 7 August 2013 (UTC)
