Laser Flash Spectroscopy of 4-Nitrostilbenes and Thioindigo Dyes; Configuration of the Triplet State in Solution
For 4-nitrostilbenes and thioindigo dyes a planar trans form (tr3) has been assigned to the configuration of the triplet state which is observed by nanosecond laser flash spectroscopy. At room temperature the tr3
