We propose a procedure to deduce the symmetry of ionized orbitals of the C(s) and C(2) point groups from the photoelectron angular distributions for several molecular alignments. The strategy is intentionally developed for the (n + 1') resonance enhanced multiphoton ionization, but is applicable for the case where the initial molecular alignments are well defined. Numerical calculations for valence orbitals of a nucleobase, adenine, show that only a few moderately aligned molecular ensembles are sufficient to determine the orbital symmetry.
