“…Appropriate calculations were made on the basis of molecular constants of rovibronic structure of the A 1 Π 140 Detailed description of their properties and applications was presented in our previous work. 73 Figures 5 and 6 as well as Figures 7 and 8 present functions: f Q (J) with f PR (J) and g Q (J) with g PR (J), for the v = 0 and 1 vibrational levels, respectively. Uncertainties of single measurements are negligibly small in the scales used in these graphs.…”

The 1-v″ progression of the Ångström band system, so far unobserved in the rare (13)C(17)O isotopologue, was obtained under high resolution as an emission spectrum using a high accuracy dispersive optical spectroscopy. In the studied region 22,700-24,500 cm(-1), 146 spectral lines were observed, among which 118 were interpreted as belonging to the 1-0 and 1-1 bands of B-A system, and the next 28 were interpreted as extra lines belonging to the 1-1 band of B(1)Σ(+)-e(3)Σ(-) intercombination system, also unobserved in the (13)C(17)O molecule so far. All those lines were precisely measured with an estimated accuracy better than 0.0025 cm(-1), and rotationally analyzed. As a result the following in the (13)C(17)O molecule were calculated for the first time: the merged rotational constants B1 = 1.790227(23) cm(-1), D1 = 6.233(47) × 10(-6) cm(-1), and ΔG1/2 = 2010.9622 (69) cm(-1) and the equilibrium constants, ωe = 2076.04(57) cm(-1), ωexe = 32.54(28) cm(-1), Be = 1.824678(15) cm(-1), αe = 2.2967(24) × 10(-2) cm(-1), De = 5.226(25) × 10(-6) cm(-1), and βe = 6.71(48) × 10(-7) cm(-1) for the B(1)Σ(+) Rydberg state, as well as the individual rotational constant B0 = 1.50485(78) cm(-1), and the equilibrium constants ωe = 1463.340(21) cm(-1), Be = 1.49902(12) cm(-1), αe = 1.7782(49) × 10(-2) cm(-1), De = 7.36(56) × 10(-6) cm(-1) for the A(1)Π state, and σe = 21,854.015(51) cm(-1), RKR turning points, Franck-Condon factors (FCF), relative intensities, and r centroids for the Ångström band system. With the help of the strong and vast A(1)Π (v = 0) ∼ e(3)Σ(-) (v = 1) interaction, the experimental parameters of the e(3)Σ(-) (v = 1) perturbing state were established in the (13)C(17)O molecule for the first time.

“…This high accuracy dispersive optical spectroscopy measurement system has been assembled and calibrated in our laboratory for the couple of last years. Apart from examining the carbon monoxide molecule [23] it has also been used do analyse the very little known AlH molecule [2527] and AlH + ionic molecule [28] as well as CD radical molecule [29]. Simultaneously recorded thorium atomic lines [30], obtained from several overlapped orders of the spectrum from a water-cooled, hollow-cathode tube were used for absolute wave number calibration.…”
