A new method of diagonalisation of the XY-Hamiltonian of inhomogeneous openlinear chains with periodic (in space) changing Larmor frequencies and couplingconstants is developed. As an example of application, multiple quantum dynamicsof an inhomogeneous chain consisting of 1001 spins is investigated. Intensitiesof multiple quantum coherences are calculated for arbitrary inhomogeneouschains in the approximation of the next nearest interactions.  {\it Key words:} linear spin chain, nearest--neighbour approximation,three--diagonal matrices, diagonalisation, fermions, multiple--quantum NMR,multiple--quantum coherence, intensities of multiple--quantum coherences.  {\it PACS numbers:} 05.30.-d; 76.20.+qComment: 21 pages + 1 figure (to download separately via ps-format
