title: High-resolution Fourier-transform emission spectroscopy of the A(1)II-X(1)Σ(+) system of AIH.
abstract: The emission spectrum of the A(1)II-X(1)Σ(+) system of AIH, excited in a hollow-cathode discharge lamp, has been observed at high resolution with a Fourier-transform spectrometer. The rotational lines in the 0-0 and the 1-1 bands have been measured with a precision of ±0.001 cm(-1). The present measurements provide a considerable improvement overthe previous data of Zeeman and Ritter [Can. J. Phys. 32, 555 (1954)]. The present data, combined with the previous high-resolution measurements of the 1-0 vibration-rotation band by White et al. [J. Chem. Phys. 99, 8371 (1993)] and the J = 1-0 pure rotational line of Goto and Saito [Astrophys. J. 452, L147 (1995)] have been used to determine improved molecular constants for the A(1)!! state.
