Isotopieeffekte im Rotationsspektrum des SiS / lsotopic Effects in the Rotational Spectrum of SiS

Abstract

Abstract Corrections resulting from the breakdown of the Born-Oppenheimer approximation were obtained by a detailed discussion of the higher order isotopic effects of the rotational constant Y01 . This analysis yields the sign of the electric dipole moment to be positive (+SiS-) and the sign of the molecular gJ-value to be negative. The magnitude of the adiabatic correction was evaluated.
