01/18/2025 | cbarnes | Hi,
I am working on FSD of FTIR Amide I band to find overlapped peaks. I am working with the Auto gamma value, and trying different smoothing filter values. I would like to know more about the mathematical model of the smoothing filter, and also how to calculate the enhancement factor that I am applying on my spectrum by combining the gamma value and the smoothing factor. Thank you! :) |

Origin’s Fourier Self-Deconvolution App also uses Lorentzian model. The reference is Transforms in Spectroscopy. J. Kauppinen, J. Partanen, chapter 12. The algorithm is the same but the options we provide are little different from software you mentioned. “Gamma” option in this App is the Lorentzian FWHM, which can be used to adjust the bandwidth, and the “Smoothing Factor” is used to reduce noise.
Currently Fourier Self-Deconvolution App is Pro only. |

01/14/2025 | b_j_a | Hi, I'm wondering if it's possible to add different deconvolution algorithms? I use other software that lets me deconvolute using a Lorentzian model and adjust the bandwidth and noise reduction factor. I'm wondering if origin can replicate this functionality. I'm also wondering if this app can be made available for origin (not pro). |

10/07/2023 | OriginLab | Hi 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 |
