Description:

PURPOSE

This tool can be used to find overlapping peaks in the spectrum. The position and integrated area for each peak are preserved in the deconvolved spectrum.

INSTALLATION

Download the file FourierSelfDeconvolution.opx, and then drag-and-drop onto the Origin workspace. An icon will appear in the Apps Gallery window.
NOTE: This tool requires OriginPro.

OPERATION

  1. Click the Fourier Self-Deconvolution icon in the Apps Gallery window to open the dialog.
  2. Choose XY data for the spectrum.
  3. A default value is provided for Gamma, the line shape width. Uncheck Auto checkbox to specify a custom value. The line shape will be used to deconvolve the spectrum. Generally the larger Gamma is, the narrower the deconvolved peak becomes.
  4. Specify Smoothing Factor to smooth the deconvolved spectrum. Smoothing factor must be between 0 and 1. The larger the factor, the smoother the deconvolved spectrum, and the wider the deconvolved peaks.
  5. Click Preview button to display the deconvolved spectrum. Click OK button to create the deconvolved result.

NOTES
1. X data must be evenly spaced, otherwise the result may not make sense.
2. Baseline must be subtracted before the analysis.

10/07/2023OriginLabHi Eshani2020,
To use the tool, the X data of spectrum must be evenly spaced. If your X data is not evenly spaced, you can try to use the Interpolation tool to create a uniform linearly spaced interpolated curve from your spectrum first.
Please refer to this page: https://www.originlab.com/doc/Origin-Help/Math-Inter-Extrapolate

09/29/2023Eshani2020What does it mean by . X data must be evenly spaced, otherwise the result may not make sense. and How can I fix it? Thank you
