The emission spectrum of the B2Σ+-X2Σ+ (First Negative) system of the molecular ion 12C18O+ have been photographed at a resolution sufficient to observe the spin splitting of the lines with N > 18. Four bands, 0-1, 0-3, 1-4 and 2-5, have been rotationally analyzed and the molecular constants of the B2Σ+ , v = 0,1, 2 and X2Σ+ , v =1, 3, 4, 5 have been obtained. 相似文献

Single-mode cw dye laser excitation spectra of the (0, 0), (1, 1), and (2, 2) bands of the B2Σ+-X2Σ+ system of CaCl have been observed and assigned. Some 300 independent photo-luminescence spectra have been used in making the rotational assignment and demonstrate the power of the technique of line-by-line analysis in unraveling complex spectra. Spectroscopic constants (cm?1) obtained from a weighted least squares fit of the data are given below. Numbers in parentheses refer to 95% confidence limits in the last digit.
