The incommensurate (I) states of the triple charge density waves (CDW) in IT-TaS.are studied in details by taking into account a sufficierntly large number of harmonics. Adomain-like structure of the I-CDW state is shown 1.o be realized as the fundamentalwave vector of the I state approaches to the commensurate ("3 x 1" superstructure)wave vector; the domain boundary is characterized generally by a change of the phaseand amplitude. of the CDW, and inside the domain an approximately commensurateCDW is stabilized. The nature of the commensurabi].ity energy ?tnd the coexistence ofthree CDW's are reflected in the pattern of the domain-like strtucture. The successivefirst-order transitions in IT-TaS. are discussed in this connection. The presence of adomain-like structure, which our theory predicts for the nearly commensurate phase ofIT-TaS., is consistent with the recent X-ray photoemission experiment by Hughes andPollak.
