Abstract: Using our preliminary assignment and analysis of diode laser and Fourier transform spectra of the $12 \mu m$ region of ehtane, an extended model for $\nu_{9}+\nu_{4}-\nu_{4}$ has been constructed and applied to the analysis. Interactions between the upper levels of $\nu_{9}+\nu_{4}$ and those of $3\nu_{4}, 4\nu_{4}, 5\nu_{4}$ and $6\nu_{4}$ are included in the current model. Calculated values for the interaction constants have been determined from a combination of a priori calculation results and analysis of torsional splitting data. These interaction constants as well as the calculated $\nu_{4}$ overtone levels are used as fixed parameters in a simultaneous 24 state analysis. The analysis of 1349 upper state energy levels of the hot band yields a standard deviation of $0.0957 cm^{-1}$. This result includes several localized resonances which are probably due to the interaction of $\nu_{9}+\nu_{4}$ levels with $\nu_{12}$ levels. When these locally perturbed levels are removed, the remaining 1098 levels yield a standard deviation of $0.009 cm^{-1}$. The current state of the analysis will be discussed; the analysis methods will be described.
