An `FID` where amplitude is described by `e^(-kt)` will have width at half maximum of `k/pi`. So if you want to broaden the line by `LB` Hz you'll have to make `k=pi*LB` and the apodization formula will be `e^(-pi*LB*t)`

An FID where amplitude is described by e^(-kt) will have width at half maximum of k/pi. So if you want to broaden the line by LB Hz you'll have to make k=pi*LB and the apodization formula will be e^(-pi*LB*t) $e^(-piLBt)$

An exponentially decaying FID where amplitude is described by e^(-kt) will have width at half maximum of k/pi. So if you want to broaden the line by LB Hz you'll have to make k=pi*LB and the apodization formula will be e^(-pi*LB*t)

An exponentially decaying FID where amplitude is described by e^(-kt) after FT will have give a peak with width at half maximum of k/pi. So if you want to broaden the line by LB Hz you'll have to make k=pi*LB and the apodization formula will be e^(-pi*LB*t)
