INFRARED STUDY OF THE N-15 ISOTOPIC-SPECIES OF NITRIC-OXIDE NEAR 5.4-MU-M

The 1-0 and 2-1 transitions of the 15N16O molecule have been investigated with a Fourier spectrometer (resolution 2.7 × 10-3 cm-1). The 1-0 transition of the 15N17O and 15N18O molecules have also been observed. A direct approach method was used to determine molecular constants from the observed data. The parameters AJe and γe were calculated by combining the 14N16O and 15N16O results. Two spectral coincidences with 13C16O laser lines have been found. © 1979.
