Abstract

The photochem. ring-opening of unsubstituted indolino-spiropyrans to the corresponding merocyanines in pentane, was followed by transient absorption spectroscopy. The temporal resoln. was better than 0.4 ps. During the pump pulse, an ultrafast unstructured absorption covered the entire measurement range 380-680 nm. From it emerged the structured absorption spectrum of a 1st merocyanine isomer, ...
