Comments:	In vivo absorbance spectra collected from whole cell Rhodobacter sphaeroides from 400nm to 1100nm.  A Lambda 35 spectrometer (Perkin Elmer) was used. 
	Please note that in Bchla-containing species the Qy transition can vary in position from ca. 800-950nm, depending on the species and growth conditions.  

Keywords:	bacteriochlorophyll c, Rhodobacter sphearoides, in vivo, purple bacteria
