Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors. Photosynthetic induction strongly affects the light compensation point of net photosynthesis and coincidentally the apparent quantumyield. If true, this would contradict the observation that the quantumyield is nearly independent of both temperature and the excitation energy. When grown in deep shade (2%) species significantly differed in their light-saturated rates of photosynthesis, apparent quantumyield and chlorophyll concentration. The dotted line represents the strain simulation results, and the solid line represents the quantumyield results. Moreover, this critical shell size correlates well with the shell size at which quantumyield is maximal. The energy-gap law thus would predict a considerably lower quantumyield in the reverse reaction than in the forward reaction. In a simple, but physically consistent semi-classical picture, the quantumyield depends on the momentum of the wavepacket (or corresponding classical trajectory) in the crossing region. In addition, there is some evidence that the critical shell thickness found in these simulations is related to the maximal values of quantumyield, as found experimentally. Its luminescence quantumyield is 0.65 in basic ethanol, 0.49 in ethanol, 1.0, and 0.68 in 94% ethanol. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.

It has been found, however, that the chemiluminescence intensity corrected for quantumyield decreases as the singlet excitation energy of the fluorescent molecule increases 6.
