Phys. Rev. Lett. 100, 227401 (2008) [4 pages]Noninterferometric Two-Dimensional Fourier-Transform Spectroscopy of Multilevel SystemsReceived 22 November 2007; published 2 June 2008 We demonstrate a technique that determines the phase of the photon-echo emission from spectrally resolved intensity data without requiring phase-stabilized input pulses. The full complex polarization of the emission is determined from spectral intensity measurements. The validity of this technique is demonstrated using simulated data, and is then applied to the analysis of two-color data obtained from the light-harvesting molecule lycopene. © 2008 The American Physical Society URL:
