Abstract A microscopic treatment of the collective degrees of freedom of nuclei beyond the S-D model space in interacting boson model is given. Following a similar line as in the case of defining the seniority particle operator, independent of the S degree of freedom in single j-shell, a modified S , D pairs and generalized OBT (operatorized Bogoliubov transformation) are introduced to separate both the S and D degrees of freedom from the rest in the model space of the nucleus spanned by a set of nucleon creation operators c^†_jm (j = j₁,j₂,. . .).
