Infrared absorption spectra of aniline, trapped in a low-temperature 5 K ar
gon matrix, have been obtained in the spectral region from 500 to 4000 cm(-
1). The aniline cation C6H7N+, was formed inside the matrix by UV laser irr
adiation. We report the first IR absorption spectroscopy of this cation in
an argon matrix: five fundamental vibrational bands were observed. (C) 2001
