New measurements of bound $\to$ continuum emission from particular vibrational levels of the $B(2\Sigma +)$ state of InAr into dissociative continua associated with the $X1(2\Pi 1/2),X2(2\Pi 3/2)$ and A$(2\Sigma +)$ states have yielded a wealth of $structure.1$ The present paper shows how such data may be analysed to determine both the repulsive short-range portions of the final-state potential energy curves and the associated transition moment functions. The methods used include an``RKR-like inversion procedure"", applicable to oscillatory continua whose intensity extrema may be associated with particular extrema of the initial-state vibrational wave $function,2$ and trial-and-error or least-squares fits of simulated spectra to $experiment,3,4$ an approach required for overlapping spectra whose intensity extrema may not be precisely located and/or uniquely assigned. The resulting potentials for the $X1(2\Pi 1/2),X2(2\Pi 3/2)$ and A$(2\Sigma +)$ states of InAr will be presented and discussed.
