SUBPICOSECOND RELAXATION OF LOCALIZED ELECTRONS IN LIQUID-AMMONIA Academic Article uri icon

abstract

  • We report the results of an experimental study of the optical bleaching of the absorption spectrum of the solvated electron in dilute Na-NH3 and Na-ND3(210-4 M) solutions by a single 1.06 psec pulse (pulse duration 6 psec, pulse energy 30 mJ). The absorption spectrum of the solvated electron was monitored in the spectral range 1100-850 nm with the time resolution 20-3.3 psec. The line broadening of the solvated electron optical band originates from homogeneous broadening effects. The relaxation time of the excited state of the solvated electron was determined to be 2 10-13 sec. This ultrashort relaxation time favors relaxation between bound states of the solvated electron center. Copyright 1975 American Institute of Physics.
