Abstract
One- and two-photon excitation (OPE and TPE) spectra of single 1,8-dip henyloctatetraene molecules in n-tetradecane (transition at 444 nm) we re recorded at cryogenic temperature. The high-power infrared light us ed for TPE changed the conditions in the sample so that the number of single molecule lines observed in OPE spectra was approximately twice the number in TPE spectra or OPE spectra with added infrared illuminat ion. Single molecules detectable under OPE and TPE, only under OPE, an d only under TPE were observed.
