Laser-Excited Fluorescence Spectra of Yttrium Monoiodide.
The rotational structure of the laser-excited fluorescence of yttrium monoiodide, recorded on a Fourier transform spectrometer, was analyzed, enabling the characterization of two excited states at T(e) approximately 20 690 and approximately 24 100 cm(-1). Observation of the ground state X(1)Sigma(+) is extended up to v = 15. A scheme for the electronic structure is proposed, involving the X(1)Sigma(+), B(1)Pi, D(1)Pi, Omega1, and possibly A((1)Delta) states. Copyright 1999 Academic Press.
