报告介绍 | 报告摘要:
I will show some of the recent results in the microwave or infrared range for those molecules, and some applications in astrophysics. We will also present recent results for the study of a two-top internal rotor, the methyl acetate molecule CH3-O-C(=O)-CH3, which has been very recently detected in the interstellar cloud Orion thanks our prediction.
Another goal of our work is to get some knowledge of the structural properties of small organic molecules or biomimetic molecules. Fourier transform microwave spectroscopy in the gas phase coupled with high level quantum chemical calculations or ab initio calculations has recently led to the precise and detailed determination of molecular structures for the lowest energy conformers of a number of molecules. In this talk, I will show results from molecules which can be considered as prototypes of odorant molecules, like isoamyl acetate (so-called “banana oil” or linalool, an acyclic mono-terpene present in lavender and other plants and emitted in the earth atmosphere. |
