Abstract:	The laser induced fluorescence spectra for the Ã(¹B₂)X̃(¹A₁) transition of van der Waals (vdW) complexes of aniline with N₂, H₂, and CH₄ have been observed. Based on the analysis of the rotational structure of the spectra, it is suggested that two vdW conformers exist for the N₂aniline complex though only one conformer is identified for the other complexes. In the electronically excited state of the CH₄aniline complex, energy level splittings are observed and attributed to the intramolecular rotation of CH₄.
