| Abstract: | The formation of an intramolecular excited complex state in 4-(9-anthrylmethyl)-N,N-dimethylaniline was investigated at high pressures. A change in the kinetics from thermodynamic control to kinetic control was observed in ethyl ether solvent. In toluene the process is kinetically controlled over the whole pressure range. Appearance of this process depends upon the solvent viscosity, suggesting a conformational change in the course of the formation of the excited complex state. |
