ABSTRACT
The electronic emission spectrum of YH has been investigated in the 690 nm to 3 μm spectral region using a Fourier transform spectrometer. The YH bands were excited in an yttrium hollow cathode lamp operated with neon gas and a trace of hydrogen. The observed bands have been classified into three different electronic transitions: C 1Σ+–X 1Σ+, d0+(3Σ-)–X 1Σ+, and e 3[uppercase_phi_synonym]–a 3Δ. The rotational analysis of the 0–0, 1–1, 2–2, 3–3, 0–1, 1–2, and 2–3 bands of the C 1Σ+–X 1Σ+ system provided the following set of equilibrium molecular constants for the ground state: ωe=1530.456(15) cm-1, ωexe=19.4369(72) cm-1, ωeye=0.0361(9) cm-1, Be =4.575 667(38) cm-1, αe=0.091 449(23) cm-1, and re=1.922 765(8) Å. Two weaker bands with origins at 14 264.7256(49) and 12 811.5753(49) cm-1 have been assigned as the 0–1 and 0–2 bands of a new d0+(3Σ-)–X 1Σ+ electronic transition with T0=15 756.4251(49) cm-1. Three bands observed in the red region with origins at 11 377.9784(39), 11 499.3408(26), and 11 583.8294(23) cm-1 have been assigned as the 3[uppercase_phi_synonym]2–3Δ1, 3[uppercase_phi_synonym]3–3Δ2, and 3[uppercase_phi_synonym]4–3Δ3 subbands of a new e 3[uppercase_phi_synonym]–a 3Δ electronic transition. © 1994 American Institute of Physics.
