INFRARED VIBRATION-ROTATION SPECTRUM OF ACETYLENE TRIMER
The infrared spectrum of acetylene trimer has been obtained in the 3 μm 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 MH...

| description | The infrared spectrum of acetylene trimer has been obtained in the 3 μm 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 MHz, which fixes the distance between the center of mass of each monomer and the center of mass of the trimer at 2.513 Å. This monomer separation is consistent with a trimer geometry of D3h or C3h symmetry, having atoms of adjacent monomer units close to van der Waals contact. © 1987. |
