Notes:
We use slightly modified versions of earlier ab initio potential energy surfaces for Ar+NH(a 1Δ) and Ar+NH(c 1Π) to investigate the bend–stretch levels of ArNH complexes, both within an adiabatic bender model and in full variational calculations. The positions of these levels are used to reinterpret the fluorescence excitation spectra reported previously [R. W. Randall, C.-C. Chuang, and M. I. Lester, Chem. Phys. Lett. 200, 113 (1992)]. The first 15 observed bands can be unambiguously assigned, with near-quantitative accuracy. The weak anisotropy in the lower electronic state [ArNH(a 1Δ)] complicates the rotational structure, since each band involves overlapped transitions out of several, nearly degenerate bend–stretch levels of the complex. © 1995 American Institute of Physics.
