Chlorophyll d, found in a specific group of cyanobacteria, absorbs the most light at roughly 697 nanometers, a slightly shorter wavelength than the absorption of the new chlorophyll.

By studying dichroism and polarization of fluorescence for chlorophyll a, b, bacteriochlorophyll and the corresponding phæophytins, these directions have been investigated.

THE spectra of the ethyl chlorophyllides, the crystalline derivatives of chlorophyll by replacement of the phytyl by the ethyl radical, are of interest as these compounds are valuable as ...

A new kind of chlorophyll that catches sunlight from just beyond the red end of the visible light spectrum has been discovered. The new pigment extends the known range of light that is usable by ...

Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could ...
