glide plane Explanation: http://pd.chem.ucl.ac.uk/pdnn/symm1/glide1.htm http://www.students.bucknell.edu/projects/xray/betatest/Plan... If the glide plane in the above figure has its normal to the screen Y direction and passes through the origin, then the effect of the symmetry element is to reverse the sign of the y coordinate (due to reflection) and to add one-half to the x coordinate (due to translation). The resulting symmetry operator, in this instance, is therefore given by 1/2+x,-y,z; and the symbol for the glide plane is a. |
