Title: Vibration-rotation spectra of [sup 13]C-containing acetylene: The [nu][sub 1]/[nu][sub 2] + 2[nu][sub 5] Fermi dyad

Abstract

High-resolution vibration-rotation spectra of [sup 13]C[sub 2]H[sub 2] have been recorded in the wavenumber regions 1100--1240, 1730--1810, 2550--2700, and 3130--3280 cm[sup [minus]1] at Doppler- or pressure-limited resolution. In these spectral ranges bands involving the [nu][sub 1] and [nu][sub 2] stretchings and the bending-stretching combination levels with [upsilon][sub 2] = 1, [upsilon][sub 4] = 1, [upsilon][sub 5] [le] 2 have been analyzed. The main purpose of the analysis was the treatment of the Fermi resonance occurring between the [nu][sub 1]([Sigma][sub g][sup +]) and the [nu][sub 2] + 2[nu][sub 5]([Sigma][sub g][sup +]) levels, detected as [nu][sub 1][l arrow][nu][sub 5] and [nu][sub 2] + 2[nu][sub 5][l arrow][nu][sub 5] hot bands in the 4-[mu]m region. The global analysis of all the observed transitions provided a set of 20 molecular parameters which fully characterize the stretching and bending-stretching combination states. The vibrational coupling terms which describe the Fermi resonance are also computed with high accuracy.
