| Abstract |
A reasonable theoretical fit to the experimental low-temperature absorption and CD spectra of the BChl a-protein from Prosthecochloris aestuarii has been obtained for the unaggregated protein trimer based on standard assumptions regarding QY transition moment directions. The fits depend to some extent upon varying the site wavelengths of the individual BChls not just in one subunit but in the entire trimer, a procedure not tried before. Features in both spectra, but especially in CD, at wavelengths longer than ≈810 nm are very strongly influenced by the intersubunit interactions of BChls 7 (in the Fenna-Matthews numbering). Unlike earlier theoretical models, which also gave reasonable fits but were based on unorthodox or incorrect assumptions, this exciton model gives every indication of being refineable by improved choices of site wavelengths and exciton-transition lineshapes. Calculated exciton-transition wavelengths and line widths are compared with values deduced from recent laser hole-burning experiments (Johnson and Small 1991). As in the case of the absorption and CD spectra, agreement is best for the long-wavelength half of the QY region. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 June 2021.
All research outputs
#7,454,066
of 22,788,370 outputs
Outputs from Photosynthesis Research
#195
of 769 outputs
Outputs of similar age
#5,408
of 18,760 outputs
Outputs of similar age from Photosynthesis Research
#2
of 3 outputs
Altmetric has tracked 22,788,370 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 769 research outputs from this source. They receive a mean Attention Score of 3.7. This one is in the 41st percentile – i.e., 41% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 18,760 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 8th percentile – i.e., 8% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 3 others from the same source and published within six weeks on either side of this one.
