The mid-infrared frequency standard using 14NmO(m=16,17,18) spectral lines*

Based on the global analysis of all available and reliable data for isotopic species 14NmO(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 14NmO(m=17,18) have the same accuracy as that for 14N16O although their data are rare due to their small natural abundance.
