✦ Synopsis

The rotationally resolved infrared spectrum of the v 3 band of the long-lived a31-I u electronic state of C 3 has been observed between 1428 and 1473 cm-~ using a tunable diode laser spectrometer. Metastable C 3 was produced in a discharge through a flowing mixture of acetylene and helium. The observed band consists of three R and three P branches, which show staggering due to A-type doubling and nuclear spin statistics. The band origin of 1449.5255( 22) cm-l is close to the value of 1455.3 cm-~ determined previously from matrix isolation experiments.
