Electron-spin resonance studies of laser-ablated titanium metal isolated in neon and argon display an intense feature which exhibits a symmetric, narrow line and a large matrix-dependent g shift. On the basis of a number of experiments, this is assigned to a matrix isolated 3d(3),F-4 Ti+ ion in an octahedral matrix environment. Although the ground state of the gas-phase Ti+ ion is 3d(2)4s(1),F-4, the assignment to the 3d(3),F-4 State is supported by the small hyperfine structure which is observed. The neon magnetic parameters are : g=1.934(1) and A (Ti-47)=64(1) MHz; for argon, g=1.972(1) and A=56(1) MHz. This unusual stabilization of an excited atomic state by a rare gas matrix is consistent with ab initio studies, and has been previously found for atomic nickel. A crystal-field study of the expected behavior of a d(3),F-4 ion isolated in a tetrahedral, octahedral, or cuboctahedral environment supports the assignment to an octahedral Ti+(Rg)(6) species, and using the atomic spin-orbit parameter, zeta permits accurate values of Dq to be derived from the measured g values. Finally, it is also noted that for small values of Dq/(Dq+zeta), or for a d(3),F-4 ion in a tetrahedral environment, an as yet unobserved, unequal Zeeman splitting of the fourfold degeneracy occurs, causing a departure of the Zeeman energies from the standard formula of E(Zeeman)=beta(e)H(0)gM, with M = +/-3/2, +/-1/2. For these situations it becomes necessary to define two values of g, corresponding to the more strongly (g(3/2) and less strongly (g(1/2)) affected Zeeman levels, respectively.
