Photosynth Res
. 2014 Jan;
10(3):283-90.
PMID: 24435374
Excitation energy distribution in Porphyridium cruentum in state 1 and state 2 was investigated by time resolved 77 K fluorescence emission spectroscopy. The fluorescence rise times of phycoerythrin, phycocyanin and...

Photosynth Res
. 2014 Jan;
10(3):233-42.
PMID: 24435370
The possible origins of the different fluorescence decay components in green plants are discussed in terms of a random walk and Butler's bipartite model. The interaction of the excitations with...

Photosynth Res
. 2014 Jan;
27(3):157-68.
PMID: 24414688
The 77 K picosecond fluorescence of intact Chlamydomonas reinhardtii exhibits a 680-nm band (F680) that can be identified with light-harvesting chlorophyll. Analysis of the time and spectral dependence of F680...

Holcomb C, Knox R
Photosynth Res
. 2013 Nov;
50(2):117-31.
PMID: 24271930
In studies on photosynthetic systems it is common practice to interpret the results of time-resolved fluorescence experiments on the basis of compartmental, or target, models. Each compartment represents a group...

Photosynth Res
. 2013 Nov;
48(1-2):35-9.
PMID: 24271283
Among his many contributions to photosynthesis, William Arnold made critical suggestions about the mechanism of the initial stages of excitation energy transfer and its measurement. Thus he helped found not...

Gulen D, Wittmershaus B, Knox R
Biophys J
. 2009 May;
49(2):469-77.
PMID: 19431667
The problem of singlet excitation kinetics and dynamics, especially at high excitation intensities, among a small number of chromophores of a given system has been addressed. A specific scheme for...

Radiat Res
. 1991 Jun;
126(3):296-303.
PMID: 2034787
Effects of oxygen consumption in photodynamic therapy (PDT) are considered theoretically and experimentally. A mathematical model of the Type II mechanism of photooxidation is used to compute estimates of the...

. 1989 Jul;
50(1):45-53.
PMID: 2527374
Hematoporphyrin derivative (HPD) and other porphyrin samples were excited by 20-ps 532-nm laser pulses. Fluorescence was detected using a low-jitter streak camera. Data were fitted to a sum of exponential...

PMID: 3926017
The fluorescence of purified biliproteins (phycocyanin 645, phycocyanin 612, and phycoerythrin 545) from three cryptomonads, Chroomonas species, Hemiselmis virescens, and Rhodomonas lens, and C-phycocyanin from Anacystis nidulans has been time...

Biophys J
. 1978 Dec;
24(3):689-712.
PMID: 737283
Many cells and cell fragments are known to assume specific alignments with respect to an applied magnetic field. One indicator of this alignment is a difference between the intensities of...
