Abstract:

An electron spin resonance ESR spectrum baseline correction routine is presented for use in modeling correcting experimental ESR spectral data. The routine corrects for baseline intensity drift by approximating the baseline using a Chebyschev power-series polynomial expansion. The correction routines source code is written in FORTRAN 77 and accepts computerized ESR spectral data as input from files written in ASCII format. After correcting the baseline to zero intensity, the routine outputs ASCII files containing the corrected ESR spectral data, the baseline intensity data, and the Chebyschev coefficients for use in subsequent analyses., The algorithm used to implement the Chebyschev polynomial baseline correction and the utilities needed to perform the calculation are described and serve as a guide to the user for both routine operation and subsequent modification of the computer source code to a particular application.
