Abstract : Matrix isolation spectra in solid argon were obtained on 018 enriched Th02. From the resulting spectra it appears that the molecule is highly bent. Frequencies were assigned to the vsub1 and vsub3 vibrational fundamentals for all the various isotopic species. vsub2 was not observed in the frequency region (2 microns to 55.5 microns) covered and must be presumed to be less than 180/cm. Modifications of our spectroscopic equipment were made and it is now possible to obtain infrared spectra down to 180/cm. Examination of the long wavelength regions of the spectra of MgF2 and A1F3 using this modified equipment was made and additional spectra for lithium fluoride obtained. Resonance line studies were initiated on ZrN in a manner completely analogous to that used in the TiN study. However, much difficulty was encountered because of the reaction of the ZrN with carbon. Modifications of the furnace are being made to try to mitigate this reaction.
