My problem is calculating the area under the peaks in my FT-IR analysis. I usually work with Origin but I would like to see if I get a better result working with Python. The data I'm using is linked here and the code is below. The problem I'm facing is, I don't know how to find the start and the end of the peak to calculate the area and how to set a Baseline.
I found this answered question about how to calculate the area under multiple peaks but I don't know how to implement it in my code: How to get value of area under multiple peaks
import numpy as np
from numpy import trapz
import matplotlib.pyplot as plt
import pandas as pd
df = pd.read_csv(r'CuCO3.csv', skiprows=5)
print(df)
Wavenumber = df.iloc[:,0]
Absorbance = df.iloc[:,1]
Wavenumber_Peak = Wavenumber.iloc[700:916] #Where the peaks start/end that i want to calculate the area
Absorbance_Peak = Absorbance.iloc[700:916] #Where the peaks start/end that i want to calculate the area
plt.figure()
plt.plot(Wavenumber_Peak, Absorbance_Peak)
plt.show()
Plot of the peaks to calculate the area:
