摘要
We analyze the two-dimensional (2D) line shape obtained by 2D Fourier transforming the time-domain response of a photon-echo signal as a function of the two coherence periods, t(1) and t(3). The line shape obtained for a two-level system with homogeneous and inhomogeneous broadening is shown to be sensitive to the magnitude of both of these line-broadening mechanisms. It is shown that the ellipticity of the 2D line shape can be related to the ratio of homogeneous to inhomogeneous broadening. (C) 1999 Elsevier Science B.V. All rights reserved.
