Formation and decay rate constants of the DODCI photoisomer are found to follow an Arrhenius law with respectively an activation energy of 4.5 f 0.4 k&/M and 14 f 0.3 kcal/M. On the basis of these results a kinetic scheme is proposed for DODCI photoisomerisation. It appears from measurements of the

We report laser action of DODCI at room temperature. Intense femtosecond UV pulses provide the excitation source.

The fluorescence of the first excited state of both the normal (N) and the photoisomer (P) forms of 3,3'-diethyloxadicarbocyanine iodide (DODCI) were analyzed under steady state conditions. Argon ion laser and argon ion pumped dye laser were used for excitation. The long wavelength fluorescence, bel
