It has been shown that the expansion of a radiation field in a series of electric and magnetic multipole fields can be conveniently obtained by so-called Debye potentials, in the absence of group theory and vector harmonics. While this makes the treatment in a way more "elementary," the true nature of multipole fields is best expressed by their transformation properties in the same way as spherical harmonics of degree 1 are characterized by the property that under a rotation they transform according to a (2l + 1)dimensional irreducible representation. A group-theoretical method is illustrated which leads in a logical straightforward way to the use of Debye potentials. (B.O.G.)
