Unidentified infrared emission bands are ubiquitous in many astronomical sources. These
bands are widely, if not unanimously, attributed to collective emissions from polycyclic …

To date, 241 individual molecular species, composed of 19 different elements, have been
detected in the interstellar and circumstellar medium by astronomical observations. These …

Much like six-membered rings, five-membered rings are ubiquitous in organic chemistry,
frequently serving as the building blocks for larger molecules, including many of biochemical …

We present laboratory rotational spectroscopy of five isomers of cyanoindene (2-, 4-, 5-, 6-,
and 7-cyanoindene) using a cavity Fourier transform microwave spectrometer operating …

As the inventory of interstellar molecules continues to grow, the gulf between small species,
whose individual rotational lines can be observed with radio telescopes, and large ones …

Abstract Benzonitrile (c-C6H5CN, where 'c'indicates a cyclic structure), a polar proxy for
benzene (c-C6H6), has the potential to serve as a highly convenient radio probe for …

Stellar systems are often formed through the collapse of dense molecular clouds which, in
turn, return copious amounts of atomic and molecular material to the interstellar medium. An …

Context. Detailed astrochemical models are a key component to interpret the observations of
interstellar and circumstellar molecules since they allow important physical properties of the …

We present a study of the isocyano isomers of the cyanopolyynes HC 3 N, HC 5 N, and HC 7
N in TMC-1 and IRC+ 10216 carried out with the Yebes 40m radio telescope. This study has …

Using data from the Green Bank Telescope (GBT) Observations of TMC-1: Hunting for
Aromatic Molecules (GOTHAM) survey, we report the first astronomical detection of the C 10 …
