IP determination and 1+1 REMPI spectrum of SiO at 210–220 nm in an ion trap: Implications for SiO+ ion trap loading

Autor: Ivan Antonov, Brian Odom, Patrick Stollenwerk

Publikováno v: Journal of Molecular Spectroscopy. 355:40-45

The 1+1 REMPI spectrum of SiO in the 210–220 nm range was recorded. Observed bands were mostly assigned to the vibrational bands v ″ = 0 - 3 , v ′ = 5 - 10 of the A - X electronic transition. Additionally, a band near 216–217 nm was tentative

Improved optical control of molecular quantum states promises new applications including chemistry in the quantum regime, precision tests of fundamental physics, and quantum information processing. While much work has sought to prepare ground state m

We propose an optical pumping scheme to prepare trapped $\mathrm{AlH}^+$ molecules in a pure state, the stretched hyperfine state $\lvert F=\frac{7}{2},\, m_F=\frac{7}{2}\rangle$ of the rovibronic ground manifold $\lvert \mathrm{X}^2\Sigma^+,\, v=0,\

Cooling of a Zero-Nuclear-Spin Molecular Ion to a Selected Rotational State

Autor: Y.-W. Lin, Sruthi Venkataramanababu, Patrick Stollenwerk, Ivan Antonov, Brian Odom

Publikováno v: Physical review letters. 125(11)

We demonstrate rotational cooling of the silicon monoxide cation via optical pumping by a spectrally filtered broadband laser. Compared with diatomic hydrides, SiO\+ is more challenging to cool because of its smaller rotational interval. However, the
