Emission anisotropy spectra for Cy5-DNA in buffer solution obtained with one- and two-photon excitation. The high anisotropy values indicate a low mobility of Cy5-DNA molecules. The ratio of two-photon to one-photon anisotropies is very close to 10/7, the theoretical value for parallel transitions.
