Removing Spikes from Raman Spectra with Python: A Step-by-Step Guide
Introduction
Spike removal is an essential part of Raman data preprocessing. Spikes, caused by cosmic rays impacting the detector, appear as intense, narrow peaks that can distort the analysis. These bursts of energy hit the charge-coupled device (CCD) camera, creating sharp, high-intensity peaks that, if left uncorrected, can interfere with further processing steps like normalization, spectral search, or multivariate data analysis.
