Revised molecular constants and term values for the X-3 Sigma(-) and A(3)Pi states of NH

Research output: Contribution to journalArticlepeer-review

Abstract

The vibration-rotation spectra of NH have been reinvestigated using laboratory spectra and infrared solar spectra recorded from orbit by the ACE and ATMOS instruments. In addition to identifying the previously unobserved 6-5 vibration-rotation band in the laboratory spectra, many additional high N rotational lines have been observed. By combining the new observations with the previously published data and recent far infrared data, an improved set of molecular constants and term values have been derived for the X-3 Sigma(-) and A(3)Pi states.
