In connection with certain forms of spectroscopy (that is, circular dichroism and magnetic circular

dichroism) it is necessary to know what electronic transitions are magnetic dipole allowed. The

operators for this have the symmetry properties of Rx, Ry, and Rz. For a molecule of Td symmetry,

determine what pairs of states could be connected by a magnetic dipole allowed transition​
