The submillimeter-wave rotational transitions of TiCl in the ground state were observed using a double-modulation technique. TiCl was generated in a DC-discharge of a mixture of TiCl4 vapor (less than 1 mTorr) and Ar buffer gas (80 mTorr) at a cur-rent of 200 mA. The (4)Phi(3/2), (4)Phi(5/2), (4)Phi(7/2), and (4)Phi(9/2) spin components of (TiCl)-Cl-35 (upsilon = 0, 1, 2) and (TiCl)-Cl-37 (upsilon = 0) were detected. The data were analyzed using effective rotational constants for each spin component as well as with the usual N-2 reduced Hamiltonian. Recent Fourier transform and laser data were included in our fits and we confirm that the ground state of TiCl is a (4)Phi, electronic state. (C) 2001 Elsevier Science.
