Line positions and intensities in the v(12) band of ethylene near 1450 cm(-1): An experimental and theoretical study

摘要

Recently, we built a tensorial formalism adapted to the spectroscopy of X2Y4 molecules. It is based on formalisms developed in Dijon for spherical-top molecules. This approach has the advantages to allow a systematic development of rovibrational interactions and to make global analyses easier to perform. We used this tool to carry out an analysis of the v(12) band of (C2H4)-C-12 near 1450 cm(-1), both in frequencies and intensities. 1240 line positions and 871 intensities, measured in a set of spectra recorded in Brussels, with global root mean square deviations of 1.6 x 10(-4) cm(-1) and 1.88, respectively.
