“…In conclusion, we demonstrate the three dimensional magneto-optical trapping of YO. To our knowledge, this represents the first MOT of a non-fluoride molecule, broadening the horizon of chemical diversity of cooled molecules to include oxides, which are of chemical [35], atmospheric, and astrophysical [36] relevance. It also represents the first MOT for a molecule with an electronic state intermediate to the main cycling transition states, which necessitates careful consideration of repump choice in order to rapidly cycle photons wihout losing molecules to dark states.…”

We report three-dimensional trapping of an oxide molecule (YO), using a radio-frequency magneto-optical trap (MOT). The total number of molecules loaded is ∼1.5×10 4 , with a temperature of 7(1) mK. This diversifies the frontier of molecules that are laser coolable and paves the way for the second-stage narrow-line cooling in this molecule to the microkelvin regime. Futhermore, the new challenges of creating a 3-D MOT of YO resolved here indicate that MOTs of more complex non-linear molecules should be feasible as well.

“…Gole has recalculated data from Chalek and Gole (8) giving D o m (T → 0) for ScO(g) as 666.7 kJ·mol −1 . This value is in good agreement with the present value and with the JANAF (19) recommended value.…”

“…(6) Pedley and Marshall (1) considered the Knudsen effusion measurements on vaporization of Sc 2 O 3 (s) by Ames et al (7) to be unreliable. They also discounted a chemiluminescence study by Chalek and Gole (8) because chemiluminescence studies on both YO(g) and ScO(g) gave values of D o m (T → 0) inconsistent with other thermochemical studies. No other spectroscopic data are available for the dissociation energy of ScO(g).…”

“…8 For the reactions of Sc, Ti, and V with a given OX, this model predicts that the rate constants should increase as k͑Sc͒ Ͻ k͑Ti͒ Ͻ k͑V͒ since the energy differences of the 3d n−2 4s 2 state and 3d n−1 4s 1 first excited state are 1.43, 0.81, and 0.26 eV, for Sc, Ti, and V, respectively. [29][30][31][32][33][34][35][36] Recently Luc and co-workers measured the laser-induced fluorescence of ScO͑X 2 ⌺ + , v =0͒ formed by the reaction, Sc+ NO → ScO + N, in the beam-gas configuration. 9 An alternative mechanism proposed is an electron transfer mechanism.…”

The dynamics of the reaction, V(a 4FJ)+NO-->VO(X 4Sigma-)+N was studied by using a crossed-beam technique at 16.4 kJ/mol of collision energy. The V atomic beam was generated by laser vaporization and crossed with the O2 beam at a right angle. The laser-induced fluorescence (LIF) for the transition of VO(B 4Pi-X 4Sigma) was used to determine the rotational state distribution of the reaction product in the vibrational ground state. Almost pure V(a 4FJ) beam was obtained by using the mixture of NH3 with N2 as a carrier gas. Comparing the LIF spectra of VO measured for two carrier gases, i.e., NH3N2 and pure N2, it was concluded that the vibrational ground state of VO(X 4Sigma-) is formed almost entirely from the reaction of V(a 4FJ) and the contribution of the metastable V(a 6DJ) is negligible. The observed rotational distribution was similar to a statistical prior prediction, and suggested that the title reaction proceeds via a long-lived intermediate, which is consistent with an electron transfer mechanism.
