A study is made of self-trapped excitons in AgCl using cw and pulsed EPR techniques at 95 GHz. This type of spectroscopy, owing to its superior resolution and its time-resolved character, allows us to obtain detailed information about the properties of these excitons. The singlet-triplet splitting is determined with great accuracy and the result confirms that the exchange interaction, present between the electron and the hole making up the exciton, is very small. From a measurement of the dynamic properties of the exciton in the triplet state it appears that a tunneling process takes place between the different Jahn-Teller distorted configurations of the (AgCl6)4- complex at a rate of 105 s-1 at temperatures as low as 1.2 K. © 1993 The American Physical Society.
