Abstract

The J = 2 ← J = 1 and J = 3 ← J = 2 pure rotational transitions of TiO (X3Δ) and the N = 2 ← N = 1 pure rotational transition of TiN (X2Σ+) have been recorded using the technique of microwave-optical double resonance (MODR) spectroscopy. There was no evidence of Λ-doubling in the spectra of TiO and no evidence of hyperfine splitting in the spectra of TiN. An improved set of spectroscopic parameters for the ground state of these two molecules is given and are used to predict the pure rotational transition frequencies associated with low-lying rotational levels.
