Singlet-triplet separation in zirconium oxide
Abstract
Intercombination fluorescence transitions have been observed between the B 3Pi and the X 1Sigma+ states of gaseous ZrO during laser excitation of the allowed B 3Pi-X' 3Delta transition. The observed fluorescing lines and their identifications are listed for excitation of the beta2 heads. The measurements yield a value of 1099.08 plus or minus 0.08/cm for the singlet-triplet separation for (Zr-90)(O-16), with X 1Sigma+ below X' 3Delta. Appropriate symmetries are also assigned to the lambda-doubled levels of the B 3Delta state, using electric dipole selection rules and the absence of certain branches in the fluorescent spectrum.
