✦ Synopsis


We dcmonstratc transient absorption spectroscopy with picosecond time resolution and nanomctcr spectral rcsolution over the entire visible region. To resolve mu1 tiple discrepancies in the literature, we studied 3,3'-dicrhyloxadicarbocyanine iodide. We measured both cscited sinflct liFerime and ground sure deplaion and recovery. The kinetics of the two Processes are the same. The characteristic time is 1.15 f 0.15 nsec in ethanol and 560 + 70 pscc in waler. WC report lluorcscence yield dererminntions and comment on the controversy over photoisomer generation.
