Lifetime of the long-wavelength chlorophyll fluorescence
Biochimica et Biophysica Acta, 1963The fluorescence lifetime of chlorophyll in vivo and in vitro was measured with a phase fluorimeter. The lifetime in vivo of the long-wavelength emission (730 mμ) which appears at low temperature was 3.1 mμsec. It is concluded that this emission is fluorescence rather than phosphorescence as had been previously reported by Brody.

A non-fluorescent complex of chlorophyll a with plastocyanin
Biochemical and Biophysical Research Communications, 1985A complex between chlorophyll a and plastocyanin has been prepared by dialysis of mixtures of chlorophyll in Triton X-100 micellar solution with the protein. The complex appears to contain no more than one chlorophyll per plastocyanin molecule, and is non-fluorescent, whether the protein is in the oxidized or reduced state.

Intensity effects on the fluorescence of in vivo chlorophyll
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1977A technique for measuring relative quantum yields of fluorescence with a picosecond streak camera is described. We show that Chlorella pyrenoidosa exhibit an intensity dependent quantum yield when irradiated with single picosecond light pulses. This effect also occurs under conditions that inhibit the activity of the reaction centres, which can ...

Stimulated fluorescence and fluorescence quenching in chlorophyll a and bacteriochlorophyll a
Chemical Physics Letters, 1978Abstract This communication deals with the photophysical processes that take place in chlorophyll solutions under intense nitrogen laser irradiation. The effect of the pump photon density on the fluorescence yield depends strongly on the geometry of the irradiation and the sampling set-up.

Carotenoid-sensitized Fluorescence of Chlorophyll in vitro
Nature, 1958IT is well established that light absorbed by carotenoids can contribute to photosynthesis, phototaxis and the red fluorescence shown by chlorophyll A in the intact chloroplast. In Chlorella, independent measurements of both fluorescence1 and photosynthesis2 indicate a 40–50 per cent efficiency of energy transfer from β-carotene and lutein to ...

Chlorophyll Fluorescence Transients in Chloroplasts and Leaves
1991Photosynthesis is a complex process, the study of which requires the converging use of many experimental methods (see the Introduction in Chapter 10). As a directly detectable molecular property, fluorescence is largely used in physical chemistry. In photosynthesis, however, fluorescence is mainly (but not only) utilized as an indirect method, based on

Chlorophyll Fluorescence: A Probe of Photosynthesis In Vivo
Annual Review of Plant Biology, 2008The use of chlorophyll fluorescence to monitor photosynthetic performance in algae and plants is now widespread. This review examines how fluorescence parameters can be used to evaluate changes in photosystem II (PSII) photochemistry, linear electron flux, and CO2assimilation in vivo, and outlines the theoretical bases for the use of specific ...
