Notes. Wavelengths and energies taken from CDMS for NaCl: (Clouser & Gordy 1964; Uehara et al. 1989; Caris et al. 2002; Timp et al. 2012; Cabezas et al. 2016); KCl: (Clouser & Gordy 1964; Caris et al. 2004; Barton et al. 2014); AlO: Törring & Herrmann (1989); Yamada et al. (1990); and from the JPL Molecular Spectroscopy Database for AlOH: Apponi et al. (1993). (a) Line falls on the edge of a band, and rms is measured nearby, rather than at the line frequency, so as to exclude artefacts on the band edge. (b) Due to nearby lines, rms is measured only to one side of the listed line, to avoid contamination.
