WebI have have multiple spectra with several peaks and I am trying to fit them with lorentzian functions (one Lorentzian per peak). I am trying to automate the process for bulk analysis (i.e., using the peak finding algorithm of scipy to get peak positions, peak widths and peaks heights and use them as initial guesses for the fit). WebIn this case, the quality factor can be determined from the Fourier transform of the field by finding the resonance frequencies of the signal and measuring the full width half maximum (FWHM) of the resonant peaks. We can then use Q = f R /f where f R is the resonant frequency and f is the FWHM. Example:
