    "abstract": "We used a variety of nonlinear optical (NLO) spectroscopies to study the\nsinglet excited states order, and primary photoexcitations in polyfluorene; an\nimportant blue emitting p-conjugated polymer. The polarized NLO spectroscopies\ninclude ultrafast pump-probe photomodulation, two-photon absorption, and\nelectroabsorption. For completeness we also measured the linear absorption and\nphotoluminescence spectra. We found that the primary photoexcitations in\npolyfluorene are singlet excitons.",
