It is pointed out that many authors are unaware that the particular choice of unit-cell origin determines the irreducible representations to which octahedral tilts in perovskites belong. Furthermore, a recommendation is made that the preferred option is with the origin at the B-cation site rather than that of the A site.
需要指出的是,许多作者并未意识到,晶胞原点的特定选择决定了钙钛矿中八面体倾斜所属的不可约表示。此外,建议首选的选项是将原点置于B阳离子位点而非A位点。
