Abstract
Optical-optical double-resonance (OODR) spectra of CaF are recorded, with reduced Doppler broadening, using two cw, single-mode dye lasers. Molecular constants for E 2Σ + and E′ 2 Π are obtained from rotational analysis of the 0-0 and 1-0 E 2Σ +- A 2Π bands and the 0-0 E′ 2 Π-A 2 Π band, supplemented by fragmentary observations on the E′- A 0-1 and 1-1 bands: Main parameters E 2 Σ + E′ 2 Π T 0 34 171.218(2) 34 477.413(3) ΔG 1 2 640.912(3) 668.991(24) B e 0.364393(18) 0.368423(50) α e 0.002266(18) 0.002375(50) A(0) 16.483(4) The E′ 2 Π state is observed for the first time. Improved constants for the A 2Π state are obtained by fitting all extant rotational and vibrational information for the E′-A and A- X systems. The E and E′ states are found to obey the unique perturber rather than the pure precession relationship.
