β¦ Synopsis
The photodissociation spectrum of isolated ZrAr + has been observed. The bond length in the vibrationless ground state is r 0 = 2.718 + 0.01 A with /~" --3/2. The c state of this ion has /2' = 5/2, an electronic origin at Too = 15580 cm-1, a vibrational frequency of to e = 74.9 cm -1, an anharmonicity of toe x e = 1.15 cm-1, an equilibrium rotational constant of B e = 0.0655, and a rotation-vibration constant of a e = 0.00154 cm-1. The bond length of this excited state is r 0 = 3.050 + 0.01 .A with adiabatic bond energy of 1170 -t-20 cm -1. Assignment of the c-X band convergence places the adiabatic binding energy of ground state of ZrAr + at D o = 2706 + 20 cm -1.

The rotationally resolved photodissociation spectrum of mass-selected Ni~ has been observed. Much of the spectrum is congested and perturbed, making the assignment of spectroscopic constants difficult. However, the use of an accidental perturbation in the upper state is shown to simplify the interpr
