  • Title: [Resolution of the fluorescence and absorption spectra of chlorophyll a in the cell into its components].
    Author: Litvin FF, Stadnichuk IN, Kruglov VP.
    Journal: Biofizika; 1978; 23(3):450-5. PubMed ID: 667148.
    Abstract:
    The total number, band widths, absorption and fluorescence peak positions of universal forms of chlorophyll a in vivo were identified by means of computer curve analysis, Stepanov's relation and low temperature derivative spectroscopy. The identified pigment forms are as follows: Chl669(661), Chl676(674), Chl686(680), Chl691(687), Chl697(691), Chl706(698), Chl715(702) Chl726(709), Chl738(715) and Chl750--755(720--724) (the lower index--absorption peak position, the upper one--fluorescence peak position). The O--O electronic transitions vibronic bands energy one of the forms of chlorphyll alpha enumerated above changes for constant equal 140 cm--1.
