Abstract

{Electronic band systems of zirconium monocarbide, ZrC, in the 16000-19000cm(-1) region have been observed following the reaction of laser-ablated Zr atoms with methane under supersonic free-jet conditions. Rotational analyses of high-resolution spectra have shown that the ground state of ZrC is a (3)Sigma state, with r(0) = 1.8066 Angstrom and an unexpectedly small spin-spin parameter
