Abstract : The photography and wave-lengths measurements and analysis of the TH and T2 spectrum proceeded largely as planned. Some work was also done on the D2 spectrum. In the analysis of complicated parts of the spectra a modification of the spectrum in a discharge through 200 mm helium and traces of T2, D2 or TH was very helpful. This modified spectrum showed only bands originating from vibrationless levels at a high rotational temperature. Attempts to obtain the spectrum of T2 free from TH and H2 so far have not been successful, and a modification in the discharge tube is proposed. This modified tube should also be satisfactory for accurate intensity measurements. The analysis of the molecular spectrum of He revealed a noticeable interaction between nuclear spin and orbital angular momentum.
