![]() ![]() The only groups not having any correlation to C s (= S 1), C i (= S 2), or any of the S n ( S 4 or S 6) groupsĪre C n ( n ≥ 1), D n ( n ≥ 2), T, O, and I (not a crystallographic point group). the T h and D 2h groups are both sub-groups of O h, whereas Light grey shadings ('+') indicate, that the correlated group is correlated to another sub-group of the initial high-symmetry group ![]() May be expected from rotation, vibration, or substitution of a molecular geometry.įor example, as indicated by dark gray shading ('X'), the T h point group is a sub-group of O h (see first row of matrix). A table of this kind gives an indication which reduction of symmetry In the first column, and correlations with ' less symmetrical' groups are indicated in the corresponding row ('X' and '+'). ![]() The table below gives a full correlation matrix between the 32 crystallographic point groups, where the initial high-symmetry groups are listed Would involve purely aesthetic considerations. Otherwise, the decision if for example a C 4 symmetrical molecule is more symmetrical than one of the C 6 point group which molecular conformation or geometry) is ' more symmetrical' than another can only be answered if one point group is a ![]()
