Microwave spectra of molecules of astrophysical interest. XVIII. Formic acid

摘要: The available data on the microwave spectrum of formic acid are critically reviewed for information applicable to radioastronomy. Molecular such as derived rotational constants, centrifugal distortion constants and electric dipole moment tabulated. observed transitions presented astronomically interesting isotopic forms. Calculated up 300 GHz ground vibrational state H12C16O16OH, H12C16O16OD, D12C16O16OH H13C16O16OH. Some also listed H12C16O18OH H12C18O16OH. Estimated error limits have been reported all measured transitions.
