The dimerization of protochlorophyll pigments in non-polar solvents.
The infrared, visible and nuclear magnetic resonance spectra of protochlorophyll a and vinylprotochlorophyll a in dry non-polar solvents (carbon tetrachloride, chloroform, cyclohexane) are presentedExpand

TLDR
The existence of chlorophyll aggregates in vivo was suggested originally by Krasnovsky, Voinovskaya, and Kosobutskaya and later by the B r o d y and demonstrated by the investigation of F IGURE 1. Expand
Absorption and magnetic circular dichroism of chlorophyll a and b dimers.
The dimerization of chlorophyll a to the so-called special pair, in which the two monomers are linked together by two nucleophilic molecules (alcohol or water), leads to shifts and splittings of theExpand
Aggregation of chlorophyll in nonpolar solvents from molecular weight measurements.
The state of aggregation of chlorophylls a and b, pyrochlorophyll a, bacteriochlorophyll, pheophytin a and pyropheophytin a in a variety of nonpolar solvents has been deduced from molecular weightExpand
Bacteriochlorophyll c monomers, dimers, and higher aggregates in dichloromethane, chloroform, and carbon tetrachloride
TLDR
Bacteriochlorophyll c in vivo is a mixture of at least 5 homologs, all of which form aggregates in CH2Cl2, CHCl3 and CCl4, where the 4-n-propyl homolog (R-configuration) forms dimers absorbing at ca. Expand
The Pi electron structure and absorption spectra of chlorophylls in solution
This paper reviews the spectra of and proposes new assignments for the electronic absorption spectra of protochlorophyll, chlorophyll !• bacteriochlorophyll ! and their respective pheophytins. TheExpand
LASER FLASH PHOTOLYSIS STUDIES OF CHLORIN AND PORPHYRIN SYSTEMS. I. ENERGETICS OF THE TRIPLET STATE OF BACTERIOCHLOROPHYLL *
TLDR
Flash photolysis studies in a number of labora tor ie~ have shown that 3Chl a in fluid solutions is efficiently quenched by quinones, probably via electron transfer to the quencher, and the triplet state of the chlorophyll is strongly implicated as the electron donor. Expand
State of chlorophyll a in vitro and in vivo from electronic transition spectra, and the nature of antenna chlorophyll.
TLDR
A comparison of the computer deconvoluted visible spectra of photosynthetic organisms with those of solutions of chlorophyll a oligomers in nonpolar media provides good evidence that antenna chlorophyLL in green plants has spectral properties that are very similar, if not identical, to those of chlorophical oligomers, (chlorophyll2)n.

Effect of biogenic photochromic electron acceptors on chlorophyll fluorescence
It is shown that the photophysical properties of chlorophyll a (Chl) depend on the nature and relative amounts of 2-methyl-1,4-naphthoquinone (MNQ) and nicotinamide adenine dinucleotide phosphateExpand
Theoretical Study of the Dimerization of Chlorophyll (a) and Its Hydrates: Implication for Chlorophyll (a) Aggregation
Dimeric structures chlorophyll (a) (Chla) and their mono- and dihydrated have been suggested to play an important role in the mechanism of photoreaction center chlorophyll special pairs PSI and PSII.Expand
