Abstract: This work has the goal of demonstrating a novel photophysical technique able to accurately measure the intersystem crossing rate and efficiency in organic molecules with nonradiative triplet states. The technique was called Consecutive Laser Pulses Excitation, and it measures the fluorescent emission of an ensemble of molecules consecutively excited by distinct laser pulses equally spaced in time. All desired information of the triplet state is indirectly determined via the fluorescence emission, which will suffer quenching depending on the magnitude of the intersystem crossing efficiency. For the calibration of the technique, Rhodamine B and two different porphyrins were used. These are new porphyrins, which had still unknown photophysical parameters. So, an extensive optical characterization was also made for these molecules
