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 `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^(-piLBt)\$ `e^(-pi*LB*t)`

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)`
