摘要：
We present a high-resolution laser spectroscopic study of the (A) over tilde B-2(2)-(X) over tilde (2)A(1) and (B) over tilde B-2(1)-(X) over tilde (2)A(1) transitions of calcium(I) phenoxide, CaOPh (CaOC6H5). The rotationally resolved band systems are analyzed using an effective Hamiltonian model and are accurately modeled as independent perpendicular (b- or c-type) transitions. The structure of calcium monophenoxide is compared to previously observed Ca-containing radicals, and implications for direct laser cooling are discussed. This work demonstrates that functionalization of aromatic molecules with optical cycling centers can preserve many of the properties needed for laser-based control.
