✦ Synopsis

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 TiCl 4 vapor (less than 1 mTorr) and Ar buffer gas (80 mTorr) at a current of 200 mA. The 4 3/2 , 4 5/2 , 4 7/2 , and 4 9/2 spin components of Ti 35 Cl (v = 0, 1, 2) and Ti 37 Cl (v = 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 r electronic state.
