Abstract
High-resolution profiles of Al II lines recorded in the infrared regio n (1800-9000 cm(-1)) by Fourier transform spectroscopy (FTS) show reso lved or partially resolved hyperfine profiles. The analysis of 10 Al I I transitions is presented here. An investigation of these structures has allowed the deduction of magnetic dipole constants and electric qu adrupole constants for six levels which are relevant to astrophysical studies and to astrophysical databases. All the results presented are new.
