 Title: THE NEAR INFRARED $Y^{2}\Sigma^{+} - X^{2}\Pi$ TRANSITION OF COPPER SELENIDE Creators: O'Brien, L. C.; Lambeth, Amanda Issue Date: 2001 Publisher: Ohio State University Abstract: The near infrared electronic transition of CuSe has been observed for the first time. The spectrum of the $Y^{2}\Sigma^{+} - X^{2}\Pi$ transition, labeled by analogy with the CuO and CuS near infrared electronic transitions, was recorded with the Fourier transform spectrometer associated with the McMath-Pierce Solar Telescope, Kitt Peak, AZ. The CuSe molecules were produced in a King-type carbon tube furnace operating at 1800 C and at a total pressure of approximately 400 torr. The electronic term energy and vibrational constants for both states will be presented.
