The bond length of ZrAr +
Abstract
The photodissociation spectrum of isolated ZrAr + has been observed. The bond length in the vibrationless ground state is r 0 = 2.718 ± 0.01 Å with Ω″ = 3/2. The c state of this ion has Ω' = 5/5, an electronic origin at T00 = 15580 cm -1, a vibrational frequency of ωe = 74.9 cm -1, an anharmonicity of ωexe = 1.15 cm -1, an equilibrium rotational constant of Be = 0.0655, and a rotation-vibration constant of αe = 0.00154 cm -1. The bond length of this excited state is r 0 = 3.050 ± 0.01 Å with a diabatic bond energy of 1170 ± 20 cm -1. Assignment of the c-X band convergence places the adiabatic binding energy of ground state of ZrAr + at D0 = 2706 ± 20 cm -1.
