  • Title: [Picosecond flash photolysis of Halobacterium halobium bacteriorhodopsin at room and low temperatures].
    Author: Kriukov PG, Lazarev IuA, Letokhov VS, Matveets IuA, Terpugov EL.
    Journal: Biofizika; 1978; 23(1):171-3. PubMed ID: 623816.
    Abstract:
    The primary stage of photoexcitation of bacteriorhodopsin from Halobacterium halobium upon the action of ultrashort (tau equal to 25 ps) laser impulse of 530 nm wavelength and of energy 2.5.10(-3) J has been studied. The primary photoproduct with a maximum of 630 nm is shown to occur in the differential spectrum in a time less than 25 ps both at room temperature (+20 degrees C) and at a low temperature (-150 degrees C).
