Abstract

$^{1}$ D. J. Greenwood and R. F. Barrow, J. Phys. B: At. Mol. Phys. 9. 2123 (1976) and references given there; G. D. Brabson and L. Andrews, J. Phys. Chem. 96, 9172 (1992).Author Institution: Department of Chemistry, University of FloridaThe zero-field splittings $^{3}\Sigma(1X_{2})-{^{3}}\Sigma(0X_{1})$ in the ground states of the three diatomic molecules $Se_{2}$, TeSe, and $Te_{3}$ have been observed in infrared absorption in neon, argon, and krypton matrices at $4K{^{1}}$ The magnetic-dipole character of these transitions was verified by the broadening effects of applied magnetic fields of up to 4T. The relative matrix shifts and Zeeman effects are discussed
