Regarding the Detection of Interstellar C4 and C5 Molecules
The Astrophysical JournalAnalysis of very high signal-to-noise ratio (S/N) spectra of reddened stars allowed us to determine an upper limit (UL) of the column density N (C _4 ).

Photoabsorption and photodissociation of molecules important in the interstellar medium [PDF]
, 1985 The photoabsorption and photodissociation cross sections of several interstellar molecules and radicals in the 105 to 210 nm region were measured. The research results accomplished are briefly described.

An Ultraviolet Study of CO Chemistry in the Magellanic Clouds
The Astronomical JournalHow does molecular cloud chemistry change with metallicity? In this work, we study the relation between molecular hydrogen (H _2 ) and carbon monoxide (CO) at 1/2 and 1/5 solar metallicity using ultraviolet absorption spectroscopy obtained as part of the

Spectroscopy of cosmological molecules
, 2023 The molecules in the interstellar medium are composed of atoms formed in supernovae. By studying the spectra of these molecules, we can better understand supernovae and the interstellar medium. This can be done in spectrometers on Earth.

The Infrared Complex Refractive Index and Band Strengths of Coronene Thin Films
The Astrophysical JournalPolycyclic aromatic hydrocarbon (PAH) molecules have long been theorized to be present in a multitude of interstellar environments. The radio-frequency detections of specific cyanosubstituted PAH molecules in the Taurus Molecular Cloud have provided new ...

The relation between interstellar OH and other simple molecules
, 2009 We discuss the close relation between the column densities of interstellar OH and CH molecules. Our results are obtained on the basis of 10 new sightlines.

Photoabsorption and photodissociation of molecules important in the interstellar medium [PDF]
, 1986 In the period from May 15, 1985 to May 14, 1986, the photoabsorption and photodissociation cross sections of the interstellar radical of SO and the interstellar molecules of HCl, H2CO, and CH3CN were measured and the results were reported in scientific ...
