: Use the Auto Preview feature. Adjust the Points of Window —a higher value creates a smoother line, but too high can broaden your Raman peaks. Step 2: Baseline Correction
To optimize your Raman spectra in Origin, follow these steps for professional smoothing and baseline correction. : Use the Auto Preview feature
: Highlight your data or click on the graph, then go to Analysis > Signal Processing > Smooth > Open Dialog . Method Selection : : Highlight your data or click on the
This removes background signals, such as fluorescence or Rayleigh scattering, which are common in Raman spectroscopy. Origin Help - Smoothing - OriginLab Make a workbook or a graph active
Smoothing helps remove high-frequency noise from jagged experimental lines without losing the core signal.
Make a workbook or a graph active. Select Analysis: Signal Processing: Smooth from the Origin menu.
: Recommended for Raman spectra as it preserves peak heights and maximum information better than simple averaging. Adjacent-Averaging : Good for simple noise reduction.
