WebbA transition is a process over time and has no end point and includes phases of assimilation and continuous appraisal as people move in, through and out. 1. The first stage to transition can be perceived to be either: Moving in: moving into a new situation or circumstances – e.g.: moving away from home and starting university. WebbThe results for both phases are compared with those obtained from similar studies of KH2PO4. Whilst it is shown that the crystal structures of RbH2PO4 and KH2PO4 (and the way they change through the transition) are closely similar, some small but important differences are revealed.
