title: [Absorption spectra of chlorophyll a adsorbed on aerosil].
abstract: The adsorption spectra of chlorophyll a adsorbed on aerosil surface have been studied. It has been supposed that the spectral properties of adsorbed chlorophyll a layers are mainly due to the interactions between the pigment molecules. The derivative absorption spectra of adsorbed chlorophyll a have been obtained. It has been determined that descrete absorption maxima of adsorbed chlorophyll a aggregates are characteristic of the native chlorophyll a. It has been supposed that the fundamental spectral forms of chlorophyll a in vivo are reproduced in adsorbed layers of the pigment.
