Choice of spectroscopic line shape model affects metabolite peak areas and area ratios. (2000)
Journal Article
Marshall, I., Bruce, S. D., Higinbotham, J., MacLullich, A., Wardlaw, J. M., Ferguson, K. J., & Seckl, J. (2000). Choice of spectroscopic line shape model affects metabolite peak areas and area ratios. Magnetic Resonance in Medicine, 44, 646-649. doi:10.1002/1522-2594(200010)44:43.0.CO;2-0

The use of Lorentzian model lineshapes leads to systematic errors in the quantification of in vivo (1)H NMR spectra. Experimental lineshapes are better modeled by the Voigt (mixed Lorentzian-Gaussian) function, leading to more accurate fits (reduced...

An analytical derivation of a popular approximation of the Voigt function for quantification of NMR spectra. (2000)
Journal Article

The approximation of the Voigt line shape by the linear summation of Lorentzian and Gaussian line shapes of equal width is well documented and has proved to be a useful function for modeling in vivo (1)H NMR spectra. We show that the error in determi... Read More about An analytical derivation of a popular approximation of the Voigt function for quantification of NMR spectra..

Use of Voigt line shape for quantification of in Vivo ‘H spectra. (1997)
Journal Article
Marshall, I., Higinbotham, J., Bruce, S. D., & Freise, A. (1997). Use of Voigt line shape for quantification of in Vivo ‘H spectra. Magnetic Resonance in Medicine, 37, 651-657. https://doi.org/10.1002/mrm.1910370504

Quantification of NMR visible metabolites by spectral modeling usually assumes a Lorentzian or Gaussian lineshape, despite the fact that experimental lineshapes are neither. To minimize systematic fitting errors, a mixed Lorentzian-Gaussian (Voig... Read More about Use of Voigt line shape for quantification of in Vivo ‘H spectra..
