Comments:	The molar absorption coefficient of Chlorophyll a dissolved in diethyl ether based on the absorbance measurements made by Junzhong Li on 12/11/97 using an Cary 3. 
	The absorbance data was normalized to have an absorption coefficient of 111700 at 427.75 nm.	
	Peaks occur at about 426.25 and 659.50 nm. 
	Molecular formula: C55-H72-O5-N4-Mg
