✦ Synopsis

The lowest fundamental level (v_{11}) in (2-{ }^{13} \mathrm{C}) allene, (\mathrm{H}{2} \mathrm{C}=-{ }^{13} \mathrm{C}-\mathrm{CH}{2}), has been studied from a high resolution infrared spectrum of the (v_{11}) band together with lower state combination differences obtained from high resolution infrared measurements of the hot bands (v_{7}+\nu_{11}-v_{11}, v_{9}+v_{11}-) (\nu_{11}, \nu_{10}+\nu_{11}-\nu_{11}), and (2 \nu_{10}+\nu_{11}-\nu_{11}). From a simultaneous analysis of 4592 energy levels and combination differences for the (v_{11}) level a set of spectroscopic constants has been obtained with a model taking into account the two types of rotational (l)-type resonance allowed for this molecule. Subband constants for the various hot bands (\nu_{7}+\nu_{11}-\nu_{11}, \nu_{9}+\nu_{11}-\nu_{11}, \nu_{10}+\nu_{11}-\nu_{11}), and (2 \nu_{10}+\nu_{11}-\nu_{11}) assigned in this study are summarized in tables.
