We report the first detection on Titan of the small cyclic molecule cyclopropenylidene (cC 3 H
2) from high-sensitivity spectroscopic observations made with the Atacama Large Millimeter …

A combination of millimeter-wave and high-resolution infrared data is used to analyze the
eight lowest-energy vibrational states of benzonitrile (C 6 H 5 CN, C 2 v, μ a= 4.5 D), a …

Titan harbors a dense, organic-rich atmosphere primarily composed of N 2 and CH 4, with
lesser amounts of hydrocarbons and nitrogen-bearing species. As a result of high-sensitivity …

The high resolution vibrational spectrum of ethyl cyanide (C 2 H 5 CN) has been
investigated in the far-IR using synchrotron-based Fourier transform spectroscopy. The …

A new millimeter-to millimeter-wave double-modulation double-resonance (MMW-MMW DM-
DR) scheme has been applied to record spectra of two astronomically relevant complex …

The rotational spectrum of 3-furonitrile has been collected from 85 to 500 GHz, spanning the
most intense rotational transitions observable at room temperature. The large dipole …

Propionitrile (also known as ethyl cyanide, CH3CH2CN) and acetylene (C2H2) are two
organic molecules that have been detected in Titan's atmosphere. Over time, they may …

The analysis of syn-2-cyano-1, 3-butadiene (C5H5N, μa= 3.2 D, μb= 2.3 D) in its ground
vibrational state and two lowest-energy excited vibrational states, ν27 (A ″, 144 cm− 1) and …

The orientation and magnitude of the molecular electric dipole moment are key properties
relevant to topics ranging from the nature of intermolecular interactions to the quantitative …

The current report covers the period from 2018 to March 2021. As with previous reports, the
current one is divided into three areas covering rotational, vibrational, and electronic …
