La desactivación de la fluorescencia del carbazol por alcaloides tropánicos en ciclohexano ha sido estudiada en estado estacionario. Los resultados obtenidos indican la formación de un complejo por enlace de hidrógeno tanto en el estado fundamental como en el excitado. Los valores de las constantes de equilibrio son Kg = 18.0 M-1 y 158 < Ke < 430 M-1 para el estado fundamental y el excitado respectivamente.
The fluorescence quenching of carbazole by tropanic alkaloids in ciclohexane has been studied in the steady-state. The results obtained supports hydrogen-bond formation both in the ground and excited states. The values of the equilibrium constants are Kg = 18.0 M-1 y 158 < Ke < 430 M-1 both for the ground and excited states respectively.
