摘要：

A Fourier transform interferometer was used to record the slit-jet absorption spectrum of (C2H4)-C-12 between 2500 and 3500 cm(-1) at a spectral resolution of 0.02 cm(-1). The rotational analysis of the nu(9) and nu(11) fundamental and nu(2) + nu(12) combination bands is performed, effective rotational parameters are presented, and relative absorption intensities are measured. In addition, a few lines of the 2 nu(10) + nu(12) band are assigned. The selective sampling of vibrational hot bands in the jet is demonstrated using another experimental apparatus, with a heated slit. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
