Radicals generated by pulse laser photo-irradiation have a very short life, so cannot be detected by magnetic field modulation methods. Time-resolved ESR can effect a time-resolution of sub microsecond by direct detection of ESR. Identification of shortlife intermediates generated in the initial stages of chemical reactions may therefore be possible.
