Dispersion versus Absorption (DISPA): Hilbert Transforms in Spectral Line Shape Analysis
Chapter 1 describes the origin and shape of a hypothetical spectral absorption signal arising from a single driven oscillator with a single natural frequency and a single relaxation time. Experimental spectra, on the other hand, often exhibit signals composed of a sum of two or more peaks of different natural frequencies and/or line widths. Most generally, one can distinguish between a superposition of lines of different position (Fig. 1a) and a superposition of lines of different width (Fig. 1b).
