A high-resolution laser ablation study of the transition of SrCCH

Laser spectroscopy of the –transitions of SrCCH and SrCCD

“…Table 1 provides the molecular parameters obtained in our analysis. Comparison of our results with the previously published analysis of the SrCCH e A 2 P-e X 2 R þ spectrum [3] revealed some unexpected differences. We found it curious that we needed only four parameters to describe the e A 2 P state of SrCCD up to N 00 < 33, while the SrCCH analysis required seven, adding D (centrifugal distortion), A D (centrifugal distortion on the spin-orbit effect) and the q K-doubling parameter even though the SrCCH data were limited to N 00 < 16.…”

“…A rotationally-resolved spectrum of the e A 2 P-e X 2 R þ transition which permitted an analysis of the e A 2 P state was reported in 2005 [3]. In this Note we report on the spectrum of the e A 2 Pe X 2 R þ transition in SrCCD following on our recent investigation of the same transition in CaCCD [4].…”

Laser spectroscopy of the and transitions of CaCCD

“…In 2005 Tokaryk, Adam, and Hopkins fully characterized the 0 0 0 and 3 1 0 bands of this transition in MgCCH [11] and Dick et al reported the high-resolution analysis of the analogous bands in SrCCH [12]. In all of these radicals, the e B 2 R þ -e X 2 R þ transition between the second excited state and the ground state is allowed, but efforts to detect this transition in CaCCH and SrCCH via laserinduced fluorescence were unsuccessful [6,12].…”

The e B 2 R þ -e X 2 R þ transition in CaCCH was later obtained at low resolution using cavity ring down laser spectroscopy [13].…”

“…For example, the pure rotational spectra of LiCCH, NaCCH, and KCCH have been recorded using millimeter/submillimeter direct absorption techniques [1][2][3][4], and their ground-state properties have also been explored theoretically [5]. The ground-and excited-states properties of CaCCH and SrCCH have been determined in detail [14][15][16][17][18][19][20][21][22][23][24]. Recently, the electronic spectrum of AlCCH in the gas phase has been measured by means of the resonant two-color two-photon ionization (R2C2PI) technique [25].…”
