Research Abstract

Variable-temperature X-ray diffraction study had already revealed that many organic molecules, such as azobenzenes and stilbenes, undergo pedal motion in crystals. In the present study we have examined the pedal motion by using solid-state NMR spectroscopy. In some cases, we have succeeded in determining the rates of conformational interconversion through the pedal motion. The activation energy of the pedal motion was estimated from the temperature dependence of the rate of the process.
