Journal ArticleDOI
Quenching of chlorophyll fluorescence and primary photochemistry in chloroplasts by dibromothymoquinone.
M. Kitajima,Warren L. Butler +1 more
TL;DR: FO and FV are the same type of fluorescence, both emanating from the bulk chlorophyll of Photosystem II, according to simple theory, which predicts that the ratio FV/FM should equal phipo.
Journal ArticleDOI
Energy Distribution in the Photochemical Apparatus of Photosynthesis
Journal ArticleDOI
Detection, assay, and preliminary purification of the pigment controlling photoresponsive development of plants.
TL;DR: The presence of the photoreversible pigment in intact tissue has been demonstrated with a recording, single-beam spectrophotometer and the system response is sufficiently reproducible that valid difference spectra can be obtained by subtracting one recorded curve from another.
Journal ArticleDOI
Fluorescence quenching in Photosystem II of chloroplasts
Warren L. Butler,M. Kitajima +1 more
TL;DR: A simple photochemical model for the photosynthetic units of Photosystem II based on first-order rate constants for de-excitation of excited chlorophyll molecules is presented in the form of equations which predict the yields of fluorescence.
Journal ArticleDOI
Higher derivative analysis of complex absorption spectra
Warren L. Butler,D. W. Hopkins +1 more
TL;DR: In this article, a small computer on line with a single-beam spectrophotometer was used to obtain absorption spectra and higher derivatives (up to the fourth) of the absorption spectrum.
