WebIf we rotate the simple crystals by 90 o notice that the lattice and crystal look exactly the same as what we started with. Rotate it another 90 o and again its the same. Another 90 o rotation again results in an identical crystal, and another 90 o rotation returns the crystal to its original orientation. Thus, in 1 360 o rotation, the crystal has repeated itself, or looks … WebDec 1, 2010 · Such rotations suggest that the concept of the symmetry number may need to be enlarged to account for internal molecular rotations. The present section addresses these issues in the context of the classical formulation of statistical thermodynamics, while treating identical atoms as indistinguishable in the customary manner. most common blood type for irish
