High-quality ab initio potential energy surfaces were calculated and subsequently used to predict the positions of the lowest bend-stretch vibrational states of the NO(X 2 ⌸,vϭ0) -Ne complex. The vibrational wavefunctions and basis set expansion coefficients, determined within the adiabatic bender model, were then used to simulate the observed spectrum for excitation of the NO(X 2 ⌸,vϭ2) -Ne complex. The overall position and rotational substructure matches well the experimental results for this
