Popis:	We have observed the NMR lineshape for 109 Ag in the paraelectric, incommensurate and commensurate phases of the 3 q incommensurate insulator proustite (Ag 3 AsS 3 ). In the paraelectric phase we observed discrete narrow lines representative of the six Ag sites in the unit cell. In the incommunsurate region the narrow lines are replaced by two broad, featureless peaks, typical of a 3 q incommensurate modulation. This is the first observation of such incommensurate line broadening for a dipolar nucleus in an insulator. In the commensurate region a larger number of discrete lines are observed, indicative of an increase in the size of the unit cell.
