Feedback Optimization Strategy for Rotational Alignment Echo Spectroscopy
Advanced Photonics Research, 2023 The recent discovery of rotational echoes has contributed to extend the applications of field‐free molecular alignment to short time scales, namely to a temporal region preceding the first alignment revival of the molecule. Most echo measurements require

From the laboratory to the interstellar medium: a strategy to search for exotic molecules in space
Frontiers in Astronomy and Space Sciences, 2023 The chemistry of the interstellar medium occurs under extreme conditions and can lead to the formation of exotic molecules. These are species that on Earth are unstable and/or highly reactive. Their discovery in space is usually based on the astronomical

Seven Conformations of the Macrocycle Cyclododecanone Unveiled by Microwave Spectroscopy
Molecules, 2021 The physicochemical properties and reactivity of macrocycles are critically shaped by their conformations. In this work, we have identified seven conformations of the macrocyclic ketone cyclododecanone using chirped-pulse Fourier transform microwave ...

Terahertz Rotational Spectroscopy [PDF]
Proceedings of the International Astronomical Union, 2005 The detection of interstellar molecules relies on the precise knowledge of spectral line positions from laboratory measurements. Technical developments of recent years have led to an extension of the accessible spectral range towards shorter wavelengths. New telescopes like SOFIA, the HIFI instrument aboard the Herschel satellite, and ALMA will be used
