High-resolution Fourier-transform spectroscopy and deperturbation analysis of the A(1)Pi(nu=1) level in (CO)-C-12-O-18

High-resolution Fourier-transform spectroscopy and deperturbation analysis of the A(1)Pi(nu=1) level in (CO)-C-12-O-18

The A(1) Pi(nu = 1) level of the (CO)-C-12-O-18 isotopologue was precisely reinvestigated with two complementary spectroscopic techniques. High resolution B-1 Sigma(+) -> A(1)Pi(0, 1), (1, 1) and C-1 Sigma(+) -> A(1) Pi(0, 1) emission bands were recorded in the visible region, 20,700 - 26,100...

Zusammenfassung:The A(1) Pi(nu = 1) level of the (CO)-C-12-O-18 isotopologue was precisely reinvestigated with two complementary spectroscopic techniques. High resolution B-1 Sigma(+) -> A(1)Pi(0, 1), (1, 1) and C-1 Sigma(+) -> A(1) Pi(0, 1) emission bands were recorded in the visible region, 20,700 - 26,100 cm(-1), with a 1.71 m Fourier-transform spectrometer (Bruker IFS 125-HR) installed at the University of Rzeszow. The resulting line centre accuracy of isolated and medium to strong lines is 0.005 cm(-1). In addition, high-resolution spectra of the A(1) Pi
