Abstract: Previous work involving the rotational spectrum of 2-aminopyridine was limited to the lower frequencies of 4-40 GHz with very few lines being assigned. This work extends this earlier study. Here we present a much more extensive measurement and assignment of the rotational spectrum of 2-aminopyridine in the frequency range of 75-110 GHz. The observed frequencies have been assigned to the ground (0+ state) and the first excited state in the inversion vibration (0+ state). Measurements of these two states have been extended up to J = 46. With the newly assigned lines, significantly improved rotational constants and all five centrifugal distortion constants have been obtained. © 2003 Elsevier Inc. All rights reserved.
