Notes:
Stimulated emission spectroscopy has been used to access the intermolecular bending and stretching vibrations supported by the OH(X 2Π)+Ar(1S0) potential-energy surfaces. Manifolds of OH–Ar bending levels, correlating with the j= (3)/(2) , (5)/(2) , and (7)/(2) rotational levels of OH(2Π3/2), have been observed with zero to three quanta of intermolecular stretch. OH–Ar complexes have also been prepared in intermolecular vibrational levels of the spin–orbit excited state correlating with OH(2Π1/2). The first dissociation limit, producing OH(2Π3/2) v=0, j= (3)/(2) +Ar(1S0) fragments, has been determined to lie between 93 and 103 cm−1 above the zero-point level. Complexes prepared in metastable levels, detected up to 200 cm−1 beyond the first dissociation limit, undergo predissociation by using OH rotational or spin–orbit excitation to break the OH–Ar intermolecular bond.
