Abstract

The investigation of the photoreversible fulgide Aberchrome-540 as a function of pressure and temperature with the use of nuclear magnetic resonance (NMR) detection is described. This technique demonstrates the novel combination of high-pressure NMR and laser photolysis with the use of fiber optics for the conversion of the fulgide on-line in the instrument. Investigation of the photolysis of Aberchrome-540 to 2.0 kbar and 120 °C is reported. Extension of this technique should allow the investigation of photoinitiated reaction kinetics and equilibria as a function of pressure and temperature with simultaneous structure characterization by NMR.
