Abstract
Previous work involving the rotational spectrum of aniline was limited to the lower frequencies of 8-40 GHz with very few lines being assigned. This work extends the earlier studies. Here we present a much more extensive measurement and assignment of the rotational spectrum of aniline in the frequency range of 75-110 GHz. The observed frequencies have been assigned to the ground (0 +), first (0-), and second excited (1+) states in the inversion vibration. With the newly assigned lines, significantly improved rotational constants and all five centrifugal distortion constants have been obtained. © 2004 Elsevier Inc. All rights reserved.
