 Title: EFFECTS OF FERMI RESONANCE IN THE BANDS OF $^{15}N_{2}^{18}O$. Creators: Mantz, A. W.; Jones, L. H.; Potter, R. M. Issue Date: 1968 Abstract: In view of the excellent results obtained for the internuclear distances in nitrous oxide from a study of the $^{15}N_{2}^{18}O$ bands in the near $infrared,^{1}$ further high resolution observational data were obtained both in the near infrared ($2-3 \mu$ region) as well as at the longer wavelengths (8 micron region). In the near infrared the resolving power was such that half value widths of about $0.025- 0.03 cm^{-1}$ were measured on unblended lines. A liquid helium cooled Ge:Hg detector was used at $8 \mu$, and the resolution was slightly better than $0.05 cm^{-1}$. The effects of Fermi resonance in the $^{15}N_{2}^{18}O$ molecule will be discussed employing the observational data for the following completed polyads: $(10^{0}0, 02^{0}0), (11^{1}0,03^{1}0), (10^{0}1, 02^{0}1), (11^{1}1,03^{1}1), (20^{0}1, 12^{0}1, 04^{0}1)$.
