THE MID-INFRARED FREQUENCY STANDARD USING ¹⁴N^mO(m=16,17,18) SPECTRAL LINES

Based on the global analysis of all available and reliable data for isotopic species ¹⁴N^mO(m=16,17,18), the ¹⁴N¹⁶O rovibrational spectral lines are calculated with very high accuracy and completely agree with previous results. These lines with relative intensities can be achieved as an infrared frequency standard in the spectral range 1600-5600 cm^-1. The calculated rovibrational transitions of ¹⁴N^mO(m=17,18) have the same accuracy as that for ¹⁴N¹⁶O although their data are rare due to their small natural abundance.
