摘要

A tunable and narrowband vacuum ultraviolet laser system near λ=107.5nm is used to record Doppler-free molecular beam spectra of the E¹Π–X¹Σ⁺ (0,0) band for three isotopomers of carbon monoxide. The Q branches of the E–X (0,0) bands in ¹²C¹⁶O, ¹³C¹⁶O, and ¹³C¹⁸O are fully resolved in this study, performed at a resolution of 0.02cm⁻¹ (FWHM). The newly obtained data are included in a comprehensive fitting routine with previous data to yield optimized molecular constants for the upper level.
