The abstract I submitted: Recent improvements in both the quality and quantity of the available astrophysical data have increased the strain on the existing quantum mechanical (QM) catalogs. Numerous spectral features and lines have been observed which cannot be accounted for by the current QM catalogs. Our experimentally based approach to this problem allows for the spectrally complete analysis of these data without the need for quantum assignment/numbers. With preliminary science verification data from ALMA, we have shown that our alternative to the QM catalogs allow for species specific temperature and column density measurements. All of the spectral features across the entire frequency band from blended species, including those from isotoplogues, have been successfully modeled. This form of analysis successfully modeled methyl cyanide, ethyl cyanide and vinyl cyanide present in the Hot Core of Orion KL and found them to be in local thermodynamic equilibrium with each other \footnote{Fortman, S. M., McMillan, J. P., Neese, C. F., et al. 2012 \emph{JMoSp}, \textbf{280}, 11}. Methanol, methyl formate, ethyl cyanide, vinyl cyanide and methyl cyanide have all been fully studied in the 210 – 270 GHz band and our results are ready for their immediate use in astronomy \footnote{McMillan, J. P., Fortman, S. M., Neese, C. F. \& De~Lucia, F. C. 2014, \emph{ApJ}, \textbf{795}, 56} \footnote{McMillan, J. P., Fortman, S. M., Neese, C. F. \& De~Lucia, F. C. 2016, \emph{ApJ}, \textbf{823}, 1} \footnote{Fortman, S. M., Medvedev, I. R., Neese, C. F. \& De~Lucia, F. C. 2010, \emph{ApJ}, \textbf{725}, 1682} \footnote{Fortman, S. M., Medvedev, I. R., Neese, C. F. \& De~Lucia, F. C. 2011, \emph{ApJ}, \textbf{737}, 20}. Acetaldehyde and dimethyl ether have much work done and their results are expected within the next year. In the 550 – 650 GHz band our results on methanol and ethyl cyanide are ready for immediate use \footnote{Fortman, S. M., Neese, C. F. \& De~Lucia, F. C. 2014, \emph{ApJ}, \textbf{782}, 75} \footnote{Fortman, S. M., Medvedev, I. R., Neese, C. F. \& De~Lucia, F. C. 2010, \emph{ApJ}, \textbf{714}, 476}. We’ve made the results of our analysis, along with the original spectral scans, available in the electronic archives of ‘The Astrophysical Journal’. These archives may be accessed through the online versions of the papers sited in this abstract. We will present: the details of our experimental process, the extent to which we expand upon the existing QM catalogs and our success in modeling the complete spectra of 5 molecular species found in the Hot Core of Orion KL using ALMA’s preliminary science verification data. -- [image: The Ohio State University] James P.
