Aniline trimer

A rotational investigation of the aniline trimer was published in Angewandte Chemie. The work, done in collaboration with Cristobal Pérez (Hamburg) and Brooks Pate (Virginia), found three isomers of the aniline trimer and two isomers of the monohydrated dimer. The trimer is more complex than the analogue phenol trimer, where the stronger O-H···O interaction produce a single (symmetric) isomer. In the aniline trimer, stabilized by N-H···N and N-H···Pi, interactions one of the observed species is also a symmetric rotor.
