Abstract:
Determination of the quantum yields of Gibberellin, Hypocrellin A and phenol showed that there were respectively ranges of excitation wavelengths for the relative constant of quantum yields of them. The quantum yields of Gibberellin excited by its own multiple excitaion wavelengths (285 and 410 nm) equaled each other. The quantum yields were similar by excitation of 585 nm and 625 nm with determination of the emission at 640 nm for Hypocrellin A. The emission at 690nm with Hypocrellin A would disappear after it had stood at room temperature for about one month, it suggests that it should be convenient to determine the quantum yield, at a shorter wavelength as for the excitation maximum, of a fluorophore whose concentration was low, weak quantum yield and wavelengths of the excitation and emission locating nearly, with a strong Reilagh scattering; and that the 690 nm emission of Hypocrellin A should be emitted by the groups which were subjected to the effects of physical or chemical disturbences.
