title: Fourier Transform Spectroscopy of the Y2Sigma+-X2Pii Transition of CuO
abstract: The Y2Sigma+-X2Pii near-infrared electronic transition of CuO was observed at high resolution for the first time. The spectrum was recorded with the Fourier transform spectrometer associated with the McMath-Pierce Solar Telescope at Kitt Peak. The excited CuO molecules were produced in a low pressure copper hollow cathode sputter with a slow flow of oxygen. Constants for the Y2Sigma+ states of CuO are: T0 = 7715.47765(54) cm-1, B = 0.4735780(28) cm-1, D = 0.822(12) x 10(-6) cm-1, H = 0.46(10) x 10(-10) cm-1, gamma = -0.089587(42) cm-1, gammaD = 0.1272(79) x 10(-6) cm-1, bF = 0.12347(22) cm-1, and c = 0.0550(74) cm-1. Improved X2Pii constants are also presented.
