Large polycyclic aromatic hydrocarbon (PAH) molecules carry the infrared (IR) emission
features that dominate the spectra of most galactic and extragalactic sources. This review …

In this review, we present an overview of our recent work on the infrared spectroscopy of
mass-selected gas-phase molecular ions. The ions are stored and isolated in a quadrupole …

We present a quantitative model for the infrared emission from dust in the diffuse interstellar
medium. The model consists of a mixture of amorphous silicate grains and carbonaceous …

Using physical models, we study the sensitivity of polycyclic aromatic hydrocarbon (PAH)
emission spectra to the character of the illuminating starlight, to the PAH size distribution …

The infrared emission band spectrum associated with many different interstellar objects can
be modeled successfully by using combined laboratory spectra of neutral and positively …

Calculations are carried out using density functional theory (DFT) to determine the harmonic
frequencies and intensities of the neutrals and cations of 13 polycyclic aromatic …

ABSTRACT A significantly updated version of the NASA Ames PAH IR Spectroscopic
Database, the first major revision since its release in 2010, is presented. The current version …

Abstract The Spitzer Space Telescope was used to study the mid-to far-infrared properties of
NGC 300 and to compare dust emission to Hα to elucidate the heating of the interstellar …

We have coupled a singular value decomposition method with a Monte Carlo search
algorithm to analyse the mid-infrared ISOCAM spectral maps of photodissociation regions …

Abstract Ganoderma lingzhi (G. lingzhi), G. sinense, G. applanatum, etc. belongs to the
Ganoderma genus of polypore mushrooms which contain rich polysaccharides valuable for …
