Introduction: RamanspectroscopyisbasedontheRamanscattering phenomenon,whichoccurswhenasampleisexcitedwithlaser light.Thescatteredradiationexperiencesenergyshifts correspondingtothevibrationalmodesofthemoleculespresent inthesample,resultinginauniquespectralfingerprint.Skewness, astatisticalmeasureoftheasymmetryofadistribution,can provideinformationabouttheshape,symmetry,andmolecular interactionswithinthesample.Therefore,accuratelymeasuring andunderstandingtheskewnessofRamanspectraisofgreat importance. ExistingMethods: Currently,thereareseveralmethodsavailableforcalculating skewnessinRamanspectra.Themostcommonapproachinvolves directlycomputingtheskewnesscoefficientbasedontheraw intensityvaluesobtainedfromtheRamaninstrument.However, thisconventionalmethodoftenoverlookscertaindata preprocessingstepsthatcanimprovetheaccuracyandreliability oftheskewnessanalysis.Additionally,itfailstoaccountfor potentialnoiseandsystematicerrorspresentinthedata. ImprovedDataProcessingMethod: Toaddressthelimitationsoftheconventionalapproach,an
