✦ Synopsis

Two-pulse Hahn and three-pulse stimulated echo esperiments are performed on the impurity-induced Y-trap in 1.1.4_5-tetnchlorobenzene.

Comparison of results obtained with protonated and deuteraled trap-inducing impurities suggests that the nuclei of the impurity, which lies adjacent to the triplet trap. are detuned from the bulk nuclei, and thus do not psrticipnte in the dephasing process. In addition, Hahn echo deny modulations are observed which crm be attributed to chlorine nuclear hypertime interactions in the traps.
