نویسندگان
چکیده
Context. The primary alcohol n-propanol (i.e., normal-propanol or propan-1-ol; C 3 H 7 OH) occurs in five different conformers: Ga, Gg, Gg' , Aa, and Ag. All rotational spectra of the three conformers G family are well described, making astronomical search their spectroscopic signatures possible, as opposed to those Aa Ag conformers. Aims. Our goal is facilitate detection by characterizing spectra. Methods. We recorded frequency domain 18-505 GHz. Additional double-modulation double-resonance (DM-DR) measurements were performed, more specifically with unambiguously assign weak transitions conformer verify assignments conformer. Results. derived a quantum mechanical model experimental accuracy (with J max = 70 K ,max 6) for n -propanol. Furthermore, we assigned 69 a, 9) n-propanol; doing so, prove existence two tunneling states, + − . Conclusions. all now possible via signatures. These applied companion article on toward hot molecular core Sgr B2(N2).

Chiral rotational spectroscopy
We introduce chiral rotational spectroscopy, a technique that enables the determination of the orientated optical activity pseudotensor components BXX , BYY , and BZZ of chiral molecules, in a manner that reveals the enantiomeric constitution of a sample and provides an incisive signal even for a racemate. Chiral rotational spectroscopy could find particular use in the analysis of molecules tha...
متن کاملRotational spectroscopy meets theory.
Rotational spectroscopy is known to be a technique that is widely used to infer information on molecular structure and dynamics. In the last few decades, its role in the field of atmospheric and astrophysical investigations has rapidly grown. However, several are the challenging aspects in rotational spectroscopy, since the detection and analysis of spectra as well as interpretation of obtained...
متن کاملIndirect rotational spectroscopy of HCO+.
Spectroscopy of the ν1 band of the astrophysically relevant ion HCO(+) is performed with an optical parametric oscillator calibrated with an optical frequency comb. The sub-MHz accuracy of this technique was confirmed by performing a combination differences analysis with the acquired rovibrational data and comparing the results to known ground-state rotational transitions. A similar combination...
متن کاملPrebiotic molecules in interstellar space: rotational spectroscopy and quantum chemistry
One of the most important open issues in astrochemistry and astrobiology is the detection in space of complex organic molecules, in particular those having a strong prebiotic role (i.e., related to the formation of biomolecule building blocks), and the identification of the chemical routes for their production. By means of selected examples, the role of rotational spectroscopy and quantum chemi...
