The chlorophyll triplet state as a probe of structure and function in photosynthesis.
TLDR
This review has tried to emphasize work on the triplet state of chlorophyll in photosynthetic and related systems which has appeared since previous reviews were published, and to demonstrate the impact that the newly available crystal structure has had on many of these studies.About:

TL;DR: Targeted inactivation of the menA and menB genes, which code for phytyl transferase and 1,4-dihydroxy-2-naphthoate synthase prevented the synthesis of phylloquinone, thereby confirming the participation of these two gene products in the biosynthetic pathway.

New EPR methods for investigating photoprocesses with paramagnetic intermediates.
Dietmar Stehlik,Klaus Möbius +1 more
TL;DR: Significance and specificity of the results achieved for charge separation in photosynthetic reaction centers and donor-acceptor model complexes indicate highly promising perspectives in photochemical research.

TL;DR: The PsaA-branch mutant shows slower growth rates, higher light sensitivity, and reduced amounts of PS I, and is interpreted as being due to disorder in the A0 binding site, which leads to a distribution of lifetimes for A0- in the PsaB branch of cofactors.

TL;DR: Five sequences coding for proteins homologous to components of the respiratory‐chain NADH dehydrogenase from human mitochondria have been found and sequence and expression analyses indicate both prokaryotic and eukaryotic features of the chloroplast genes.

The energy gap law for radiationless transitions in large molecules
Robert Englman,Joshua Jortner +1 more
TL;DR: In this article, a unified treatment of non-radiative decay processes in large molecules which involve either electronic relaxation between two electronic states or unimolecular rearrangeme(s) is presented.

Spectra of porphyrins
TL;DR: In this article, the absorption spectra of metal porphyrins derived from the basic skeleton are discussed in terms of a four-orbit model, that is intensity changes and energy shifts are related to the properties of two top filled and two lowest empty pi orbitals.
