Abstract

This is is the first high resolution IR study of any band of the 2-$^{13}$C-propene species. There have been only two previous high resolution studies of vibration-rotation bands of the normal species.footnote{Ainetschian, Fraser, Ortigoso & Pate, J. Chem. Phys. textbf{100}, 729 ff. (1994); Lafferty, Flaud & Herman, J. Mol. Struct. textbf{780-781}, 65 ff. (2006).} The band examined here is the nub{14} (A') CCC skeletal bending near 421.847 wn which has an A-Type asymmetric rotor structure. The spectra were recorded on the FTS at the Far-IR beamline of the Canadian Light Source with a resolution of $Delta$$nu$ = 0.0009 wn. We have assigned and fitted around 2200 transitions and determined ground and upper state rotational constants. Lines with J up to 49 and K up to 12 were included. The subbands with K greater than 12 were perturbed and show torsional splittings that vary from small to extremely large. The fitting was done with the PGOPHER program of Colin Western.footnote{Western, J. Quant. Spectrosc. Rad. Transf. textbf{186}, 221 ff. (2017).} The GS constants are in good agreement with the MW constants reported recently by Craig, Groner and co-workers.footnote{Paper M109, 71st ISMS Symposium (2016); J. Mol. Spectrosc. textbf{328}, 1-6 (2016).}
