Observations of H+3 in dense molecular clouds
TL;DR: In this paper, column lengths, mean number densities, and temperatures of molecular clouds were estimated using infrared absorption spectroscopy along the lines of sight to six infrared sources in dense molecular clouds: AFGL 2136, W33A, Mon R2 IRS 3 and AFGL 961E.
Observations of the 2-μm unidentified lines in planetary nebulae
TL;DR: The 2.287-micron line is strongest in medium-high excitation nebulae, and is absent in very low and very high excitation, implying that the ionization potential of the parent atom or ion is about 30-40 eV as mentioned in this paper.
Detection of H218O in Jupiter
TL;DR: The first detection of 18O in the outer solar system was reported in 1980 as mentioned in this paper, where a single line of H218O in Jupiter was detected at 5.76 cm-1, and it was shown that the Jovian isotopic abundance ratio was 1-3 times the terrestrial value.
Warm high‐velocity CO in the wind of Sakurai's Object (= V4334 Sgr)
TL;DR: In this paper, the UKIRT UIST spectra of Sakurai's Object (V4334 Sgr) showed CO fundamentalband absorption features around 4.7 µm.

TL;DR: The 1.6-1.8 micron spectrum of the planetary nebula IRAS 21282+505050, a strong emitter of the unidentified interstellar bands, contains a 0.02 micron wide eimission feature centered at 1.680 micron, which is well matched by laboratory spectra of the 0-2 CH stretching mode in polycyclic aromatic hydrocarbons (PAHs) as discussed by the authors.
