| Abstract: | A high sensitive pulsed laser photoacoustic calorimeter for liquid sample has been set up in our laboratory. Using this equipment, the radiationless quantum yields of three coumarins in absolute ethanol were measured to be 0.50±0.02, 0.47±0.02, and 0.38±0.02 for C428, C47 and C120, respectively. |
