Abstract
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 actinometry standards in the study of the efficiency of photosynthesis. No report seems to have been made of their absorption spectra, except for some indirect evidence that they are different from those of the chlorophylls1.
