{{DISPLAYTITLE:fwhm2rlx.m}} __NOTOC__
Converts full width at half-maximum (FWHM) of an NMR signal into an approximation of the R2 rate.

==Syntax==

     r2rate=fwhm2rlx(fwhm)

==Parameters==

     fwhm  - full width at half-maximum, Hz

==Outputs==

     r2rate  - approximate R2 relaxation rate, Hz

==Notes==
Lorentzian line shape is assumed. Note that FWHM is not a reliable measure of the transverse relaxation rate. The value obtained from this function should be treated as an upper bound.
