内容简介

Rotational spectroscopy is arguably the most accurate high-resolution molecular spectroscopic technique due to its high sensitivity to mass distributions of molecules and molecular complexes. The inherent spectral feature with molecular fingerprint stems from the fact that even subtle differences in mass distribution (arising from isotopic substitution, isomerization, tautomerization or conformerization) can lead significant changes in the pattern of rotational transitions. Since the interaction sites and the relative arrangement of moieties can be determined without environmental bias, the method allows identifying the intermolecular forces at play. Rotational spectroscopic data are also benchmark for theoretical calculations, thanks to its intrinsic high resolution. However, the increasing size and complexity of molecules has been challenging the full interpretation of their rotational spectra. In this talk, with the recent results we have obtained, the possibilities and challenges in studies of isolated molecules and molecular complexes, via rotational spectroscopy combined with theoretical calculations, will be discussed.
