Abstract

Using Fourier-transfon-n microwave spectroscopy, the rotational spectra of diethylmethylphosphonate, diethyl ethylphosphonate, and dilsopropyl methylphosphonate have been acquired. Rotational constants have been derived, and high level ab initio calculations have been carried out in order to determine the nature of the conformers that were identified using the spectral information. Continued efforts in development of FTMW spectroscopy as a quantitative tool for gas-phase chemical agent analysis is also discussed
