A method for determining the second moment of a Raman band has been proposed. The band shape is assumed to be expressed in terms of a mathematical function, which is derived from the Fourier transform of the Kubo correlation function. Parameters in the expression are adjusted with the least squares method to fit the experimental band shape to the theoretical expression. The second moment can be obtained from those parameters determined. The advantage of the proposed method lies in that the second moment can be determined even for overlapped bands.

A new edge-corrected estimator is proposed for the second moment cumulative function K(t) introduced by RIPLW (1977, JoumrJ of tlre Royal Slatiaticd Society, SetieS B 39, 172-212). This new estimator is compared by simulation methods with existing edge-corrected estimators in the context of both K (
