A computerized on-line system utilizing time-sharing services for the signal analysis and display of the electron spin resonance (ESR) spectra of organic free radicals is described. The system provides a broad analysis capacity for arithmetic and transfer operations on spectra; curve smoothing and filtering by a moving average function; differentiation and integration functions; the addition, subtraction, and inversion of spectra; and correction factor routines required to match spectral parameters. Data collection is performed by a minicomputer housed in the laboratory which transmits this data to a large time-sharing facility for further analysis. The resultant data may be displayed in either a digital or graphic format. Applications of the programs to determine free radical spin concentrations, to analyze spectra consisting of overlapping peaks, and to enhance low intensity signals are illustrated.
