Spectroscopic properties of the cyanide anion have been calculated from h@ly correlated SCEP CEPA wavefunctions. The rotational constant B,, and the vibrational frequency v of 1zC'4N-are predicted to be 56.22 GHz and 2052 cm-'. respcctivcly, with an uncertninty of about 0.3%. The &pole moment UI the
Ab initio calculations were carried out on CCCN and CCNC in order to predict their spectroscopic constants. Both restricted and unrestricted Hartree-Fock calculations were performed, utilizing a 6-31 G\* basis set. Partial allowance for electron correlation was made by the MP2 method. Both molecules
