✦ Synopsis

Laser optoacoustic spectroscopy with microsecond pulses has been used to study the deactivation processes in 3,3'-diethyloxadicarbocyanine iodide (DODCI). The heat dissipated by the excited molecules within the period of the pulse varies with the excitation wavelength. This observation can be explained by the formation of the photoisomer of DODCI, which deactivates mainly by internal conversion.
