The microwave band spectra1of asymmetric top molecules have 2J + 1 distinct rotational energy sublevels for each value of rotational quantum nuqber J. Through application of group theory, the statimary states of rigid asymmetric rotors can be classified by the irreducible representations or by the symmetry species of the V(D2) point group (the Four-group). When performing a Wang syrnrnetrizing transformation2on the original energy matrix E(K) where k is the Raj's asymmetry parameter: a new energy matrix E'(K) may be readily obtained.
