Raman Baseline Subtraction & Peak Deconvolution Simulator

Visualizes background fluorescence polynomial baseline subtraction and multi-component Gaussian/Lorentzian peak deconvolution for Raman spectroscopy.

Interactive Spectroscopy Workbench

Toggle fluorescence background subtraction and Lorentzian/Gaussian deconvolution modes in real-time.

Raw Spectrum Baseline Subtracted

Fluorescence Intensity:

Required Inputs:

Operating Instructions:

Adjust the Fluorescence Background level to observe how raw detector baseline shifts the apparent peak-to-peak ratio.
Toggle Baseline Correction to subtract the polynomial curvature.
Toggle Peak Deconvolution to observe the separated D band (~1350 cm⁻¹), G band (~1582 cm⁻¹), and 2D band (~2690 cm⁻¹).

⚠️Simulates a normalized 3-peak synthetic carbon model in browser SVG canvas.
⚠️Asymmetric Fano line-shapes and Breit-Wigner-Fano (BWF) metallic couplings are not parameterized.
⚠️Real-world raw instrument files (.spc, .txt) should be exported and processed in OriginPro or CasaXPS for formal publishing.
