Abstract: | In recent years, doubts have been cast on the validity of the conventionally applied peak-to-peak method for dose estimation. Alternative methods are reviewed, including dose versus magnetic field plots, deconvolution using Gaussian and Lorentzian line shapes, and fitting the absorption and derivative spectra with an experimentally derived spectrum of the CO−2 radical. The latter methods most probably yield the most reliable results. Conventional peak-to-peak dose estimations are closely similar. On a 2-σ basis, nearly all methods yield statistically indistinguishable results. |
