摘要：

On the basis of CCSD(T) calculations, an accurate equilibrium geometry (uncertainties in bond lengths: ca. 0.0005 Angstrom) has been established for linear HC3P. The CP equilibrium bond length is 1.5515 Angstrom and thus slightly longer than in HCP. Harmonic vibrational wavenumbers, vibration-rotation coupling constants and l-type doubling constants are reported. Accurate groundstate rotational constants are predicted for C-13 substituted species. (C) 2000 Elsevier Science B.V. All rights reserved.
