NMR Processing: Convolution: Traficante Multiplication

Function:
 

 
The figure shows the continuous example FID after traf with LB = 0.5 or LB = 2.0, corresponding to datasets fid/115 and fid/116 in the download package.
The parameter LB should be on the order of the natural line width of the peaks.

Examples/Exercises:
 

Click on the figure to see how traf with LB = 1 applied to the synthetic dataset synth/117 in the download package affects the spectrum. The effect is similar to the Gaussian multiplication but results in a better line shape.

Properties/Purpose:

• used for resolution enhancement and signal enhancement
