Supersonic jets, Fourier-transform microwave spectroscopy

Nowadays, the combination of laser ablation with Fourier transform microwave spectroscopy techniques, in supersonic jets, has enabled the gas-phase study of such systems. In this chapter, these techniques, including broadband spectroscopy, as well as results of their application into the study of the conformational panorama and structure of biomolecular building blocks, such as amino acids, nucleic bases, and monosaccharides, are briefly discussed, and with them, the tools for conformational assignation - rotational constants, nuclear quadrupole coupling interaction, and dipole moment. 

The main objective of this chapter is to summarize the advances attained in the knowledge of the strucmre of isolated biomolecular building blocks by the combination of the experimental methods that combine laser ablation with Fourier transform microwave spectroscopy techniques in supersonic jets.
