Investigating Homonuclear Broadening in NQR with Carr-Purcell Meiboom-Gill Performed on p-Chloroaniline

We investigate the possibility of obtaining a strong homonuclear response in the NQR signal from a sample expected to have stronger broadening due to heteronuclear dipolar coupling than homonuclear coupling. Previous work, also with a powder sample, revealed a strong response from homonuclear coupling in a substance without a strong heteronuclear broadening component. This new work could expand the number of samples for which those conclusions are applicable, creating more opportunities to use NQR to measure homonuclear dipolar coupling for both material characterization and determining efficient detection procedures.
