Rotational spectroscopy of organophosphorous chemical agents: cresyl and phenyl saligenin phosphates.

Cresyl and phenyl saligenin phosphates have been probed in a jet expansion by broadband chirp-excitation microwave spectroscopy, revealing the most stable conformations and their structural properties. The rotational parameters offer a high-resolution univocal route for characterization of organophosphorous agents and a testbed for computational models.
