Abstract : Progress was made in the interpretation of the N2 bands, including a discussion of predissociations in the C(3)Pi-u state, and the relation of this state to the upper state of the Goldstein-Kaplan bands. A thorough study of the He2 molecule was carried through. Many new vibrational levels in known electronic levels, and many new electronic levels were discovered, including a number of higher members of Rydberg series. Further information was obtained on the behavior of the spectrum and structure of the third group hydrides. The emission spectrum of Cl2(+) was reinvestigated under high resolution. In spite of an unprecented exhaustive experimental study (using Cl isotopes) to examine all possible details, the spectrum still presents some puzzling features which are not yet fully understood theoretically.
