Borane reducible representation

WebA "representation" of a group is a special kind of homomorphism whose domain is the group. A "representative" of a group would be an element of the group (under some kind of equivalence relation). There is a very standard, clear, definition of "irreducible representation" for any group, and I don't think there is one for "irreducible ... WebChemistry questions and answers.

In your example subject each vector on each atom to the operation in the point group, e.g rotation, reflection etc. Count 0 if the vector is moved else count 1 if it remains unchanged and -1 if it is unchanged but just points in the other direction. Now you have the reducible representation. Webform a reducible representation composed of d one-dimensional rep-resentations. Since the A~ i are obtained from the A i by a similarity transformation, the A i themselves form a reducible representation. Case II.
