Optical anisotropy was created and detected in diluted solutions of all-trans p-carotene in n-dodecane by femtosecond pump and probe pulses. At low pump intensity the anisotropy is due to photoselection produced by one-photon absorption, and it decays with the lifetime (8 ps) of the lowest electroni
