The infrared spectrum of acetylene trimer has been obtained in the 3 urn wavelength region by observing direct absorption of color center laser radiation by a pulsed molecular beam. The rotational structure of this band was that of a planar oblate symmetric top. The B rotational constant is 1885.8 M
Rotationally resolved infrared spectra are reported for the T-shaped acetylene-HF complex in helium nanodroplets, corresponding to excitation of both the H-F and asymmetric C-H stretches. In comparison to the isolated complex, rotation about the A-axis is relatively unhindered by the helium, while o
